spring-in-action-5-samples's Introduction

Spring in Action 5 Sample Code

This is the sample code for Spring in Action, Fifth Edition, by Craig Walls (https://www.manning.com/books/spring-in-action-fifth-edition).

There is one folder for each chapter in the book—except for chapters 11 and 12, which share a source folder—each containing most or all of the sample code for that chapter.

This source code is available for download from the book’s page at Manning.com as well as in GitHub at https://github.com/habuma/spring-in-action-5-samples.

IMPORTANT: Lombok

To avoid having to write and maintain what is mostly boilerplate Java code, I’ve elected to use Lombok in all of these examples. When building from the command line, using Maven, you shouldn’t encounter any problems, as Lombok is included as part of the build process. But you will very likely encounter issues if you import these projects into your IDE.

If, after importing the projects into your IDE, you see errors complaining about missing getters, setters, constructors, or log instance variables, it’s because Lombok is not installed in your IDE. These bits of code will be generated by Lombok automatically, but your IDE doesn’t know that and complains that they are missing.

To fix the errors, simply install Lombok. Lombok has support for most common (and arguably a few uncommon) IDEs, so no matter which IDE you use, you should be covered. See https://projectlombok.org/setup/overview for details on installing Lombok in your IDE.

Anybody else encountered this problem? In processDesign method, return "design" within the error handling code would clear the ingredient list. I didn't find this when reading the book the first time.

still works without @Autowired

Hi, I commented out all the @Autowired for all the JdbcTemplate in all JdbcXXXRepository and
I also commented out the @Autowired for the constructor in DesignTacoController.
But everything still works fine. I expected a null pointer exception.
Why?

Ch07 - Add Ingredient with Traverson method throws 403 Forbidden error

I was trying to run the RestTemplate example but it halted in addIngredient() method and threw an exception while trying to post data to API. Would you explain to me the reason why I got it although the addAnIngredient() method was still working fine?

Thanks in advance

Suggestions for DesignTacoControllerTest.java in chapter 3 jpa example

I have a suggestion for this test case:
In the setup method, add these three lines after design.setName("Test Taco"):
design.setId(1L);
when (designRepository.findByName("Test Taco")).thenReturn(design);
when (designRepository.findById(1L)).thenReturn(Optional.of(design));

In the processDesign(), add these unit test cases:
Optional mytaco = designRepository.findById(1L) ;

Assert.notNull(mytaco.get(), "taco created");
Long id = mytaco.get().getId();
Assert.isTrue(id==1L,"id is 1");
Taco t = designRepository.findByName("Test Taco");
Assert.isTrue(t.getName().equals("Test Taco"), "taco is test taco");

In TacoRepository.java, add
public Taco findByName(String name);

tacoRepo.findAll(PageRequest page).getContent() in Chapter 6?

The updated TacoRepository please? What's the return type of findAll(PageRequest page) ?

Please release your example code. We can QA for you.

Taco does not have getName() and getCreatedAt() methods

chapter 3: NullPointerException when saving Taco design without ingredients

Steps to reproduce:

go to ch03/tacos-jdbc
mvn spring-boot:run
localhost:8080
click on the link "Design a taco"
set taco name: "test-taco-name"
click on the button: "Submit your taco"

Expected result:
An error appears with the text: "You must choose at least 1 ingredient"

Actual result:
Whitelabel Error Page
Logs:

java.lang.NullPointerException: null

at tacos.data.JdbcTacoRepository$$FastClassBySpringCGLIB$$59d8a28e.invoke() ~[classes/:na]
at org.springframework.cglib.proxy.MethodProxy.invoke(MethodProxy.java:204) ~[spring-core-5.0.8.RELEASE.jar:5.0.8.RELEASE]
...

Root cause:
Taco.java

...
  @Size(min=1, message="You must choose at least 1 ingredient")
  private List<Ingredient> ingredients;
...

ingredients field has @Size validation. But according to documentation for @Size validation null is considered valid. If you choose no ingredients then ingredients field will be null and it is a valid value.

jsessionid parameter appended to URLs after submitting the design form

I didn't find this jsessionid parameter the first time I read the book. That was
Spring Boot 2.0.4 of course. Now it's 2.0.6.

Anybody else found the same issue? I didn't find it on another computer. Everything is the same except the macOS version. So this is strange.

There is something wrong in Ch3 when submit design.html form.

In ch3-JPA, when I submit the form in design.html, I got this problem. java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long
I checked the boot log and I found Hibernate turn the type in java into integer. like this:
Hibernate: create table ingredient (id varchar(255) not null, name varchar(255), type integer, primary key (id))
And I saw a @bean was declared in @SpringBootApplication, there also was weird in log. like this:
Hibernate: select ingredient0_.id as id1_0_0_, ingredient0_.name as name2_0_0_, ingredient0_.type as type3_0_0_ from ingredient ingredient0_ where ingredient0_.id=?
Hibernate: insert into ingredient (name, type, id) values (?, ?, ?)
Hibernate: select ingredient0_.id as id1_0_0_, ingredient0_.name as name2_0_0_, ingredient0_.type as type3_0_0_ from ingredient ingredient0_ where ingredient0_.id=?
Hibernate: insert into ingredient (name, type, id) values (?, ?, ?)
It seems like nothing will be inserted?

Chapter 4 defining users in an In-memory user store with Spring Security 5

I sign in with the following code similar to listing 4.2

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("buzz")
                .password("infinity")
                .authorities("ROLE_USER");
    }

and get this error in Spring Security 5

java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"
	at org.springframework.security.crypto.password.DelegatingPasswordEncoder$UnmappedIdPasswordEncoder.matches(DelegatingPasswordEncoder.java:244) ~[spring-security-core-5.1.3.RELEASE.jar:5.1.3.RELEASE]

...

The recommended prefix {noop} of password solved my problem.

In spring-security-core:5.0.0.RC1, the default PasswordEncoder is built as a DelegatingPasswordEncoder. When you store the users in memory, you are providing the passwords in plain text and when trying to retrieve the encoder from the DelegatingPasswordEncoder to validate the password it can't find one that matches the way in which these passwords were stored.
...
You can also simply prefix {noop} to your passwords in order for the DelegatingPasswordEncoder use the NoOpPasswordEncoder to validate these passwords.
...
User.withUsername("user").password("{noop}user").roles("USER").build();

@Autowired missing in JdbcTacoRepository?

Is @Autwired need here for JdbcTacoRepository in chapter 3?
public JdbcTacoRepository(JdbcTemplate jdbc) {
this.jdbc = jdbc;
}

Ch03 - After changing from JDBC to JPA ingredient data is missing in database

After changing all class files and the pom.xml according to chapter 3.2, the ingredient entries are missing in the database (the INGREDIENT table). I guess that they are simply not loaded because by using JPA instead of JDBC the data.sql is not executed. I saw that here in the repository the dataLoader() method was added to the TacoCloudApplication class. That solved the problem for me. But since there is no mention of it in the book, I am very interested in understanding why I had to change this to make the code work.

Mention Lombok in README

The README files for all chapters (and/or the general README file for the repository) should mention Lombok and link to instructions for installing it in the reader's IDE.

Autowired@ needed ?

Is @Autowired missing here in OrderController's constructor in chapter 3 example?
public OrderController(OrderRepository orderRepo) {
this.orderRepo = orderRepo;
}

Clean up manuscript tags from code

During the course of writing the book, much of the source code is sucked into the manuscript via tag comments. E.g.,

// tag::all[]
...some code here...
// end::all[]

This is unnecessary now that the book is in print and since it never referred to this repository anyway. Therefore, for the sake of the reader and maintenance of the code, I should clean out the tag comments.

Chapter 6 - REST : How does Angular's build integrate with Spring's build?

Just wondered because normally you issue an ng serve command to start the Angular server. I could not find a mention of that in the chapter. Did I miss anything? Can you point me to anywhere where I can read more about it?

Chapter 2 validation problems

when you validate design template, in case of errors(empty(<5 signs) name, not important whether checkboxes are marked or not), post method return "design" without ingredients info and so the page loaded incorrect (empty fields instead input checkboxes); field name on other hand validates correctly.
model in get
{order=Order(id=null, placedAt=null, deliveryName=null, deliveryStreet=null, deliveryCity=null, deliveryState=null, deliveryZip=null, ccNumber=null, ccExpiration=null, ccCVV=null, tacos=[]), taco=Taco(id=null, createdAt=null, name=null, ingredients=null), wrap=[Ingredient(id=FLTO, name=Flour Tortilla, type=WRAP), Ingredient(id=COTO, name=Corn Tortilla, type=WRAP)], protein=[Ingredient(id=GRBF, name=Ground Beef, type=PROTEIN), Ingredient(id=CARN, name=Carnitas, type=PROTEIN)], veggies=[Ingredient(id=TMTO, name=Diced Tomatoes, type=VEGGIES), Ingredient(id=LETC, name=Lettuce, type=VEGGIES)], cheese=[Ingredient(id=CHED, name=Cheddar, type=CHEESE), Ingredient(id=JACK, name=Monterrey Jack, type=CHEESE)], sauce=[Ingredient(id=SLSA, name=Salsa, type=SAUCE), Ingredient(id=SRCR, name=Sour Cream, type=SAUCE)]}
model in post
Taco(id=null, createdAt=null, name=, ingredients=[Ingredient(id=CARN, name=Carnitas, type=PROTEIN)])

why it's happend?? It seems like "taco" thymeleaf object is only returned, losing the rest info

ps: if name>5 sign, occurs NullPointerException.

the username, password, street, city, state.... are always null

No matter what I input in the registration.html form, those personal data are never posted to this RegistrationForm and they are always null.

If you want to run Angular project in Ch6 at tacocloud-ui

install node.js and V10.13.0 is OK for me.
install Angular CLI with npm install -g @angular/cli
run the project under tacocloud-ui path with ng serve and then you will find the The serve command requires to be run in an Angular project, but a project definition could not be found. with red color.
Don't be afraid.
Stackoverflow it and you should update your angular project to 7 while this project was still in 5.
update it and more details in https://stackoverflow.com/questions/52607924/have-a-new-project-but-when-ng-serve-i-get-error

npm install -g npm-check-updates
ncu -u
ng update @angular/cli
npm install

ng serve to fire it. And access browser with http://localhost:4200
recommend to read Angular in Action by Jeremy Wilken (Manning, 2018). It's a awesome book for newer to study Angular.

design is not object of type Design in the post handler in DesignController

@PostMapping
     public String processDesign(Design design) {
 // Save the taco design...
 // We'll do this in chapter 3
 log.info("Processing design: " + design);
  return "redirect:/orders/current";
}

Shouldn be :

 public String processDesign(Taco design) {
    //codes 
}

in chapter 2, Listing 2.4.

Ch03. Converter should be mentioned

I'm following book content but can not finish the demo, and I searched a lot, youtube videos, stackoverflow posts, etc, I don't know why the demo could do that without a converter, and finally I found a converter class here.

Chapter 3 JDBC problems

In chapter 3 there isn't a mention about adding "IngredientByIdConverter" - without it the app crashes after saving taco design.
The code in JdbcTacoRepository.saveTacoInfo() often results in NullPointerException. The solution is to set flag "setReturnGeneratedKeys(true)" on PreparedStatementCreatorFactory object:

PreparedStatementCreatorFactory pscf = new PreparedStatementCreatorFactory(QUERY_SAVE_TACO, Types.VARCHAR, Types.TIMESTAMP);
pscf.setReturnGeneratedKeys(true);
PreparedStatementCreator psc = pscf.newPreparedStatementCreator(Arrays.asList(taco.getName(), new Timestamp(taco.getCreatedAt().getTime())));

what's the meaning of the word "topics" in sending messages?

When I reached chapter 8 named "Sending messages asynchronously" in Spring in Action 5,I met the word "topics" several times and still couldn't understand what's the meaning of it,so could you please make a clearer explanation?Thanks.

The sentence which emerges the word "topics" in chapter 8 for example:

Whereas RabbitMQ
deals primarily with queues in exchanges, Kafka utilizes topics only to offer pub/sub
messaging.(from 8.3 Messaging with Kafka)

getter methods are not defined in Ingredient.java

Spring Security chapter no longer works for me

In normal mode of the browser, after I submit the register form, an HTTP Error 403 happens.
In private mode of the browser, after I submit the register form, I was taken to the design URL but the error shows the user object was null.

Ingredient class does not have an argumented constructor

Hi, authors,
I noticed all Ingredient classes do not have an argument constructor , Ingredient (String, String, Enum) and there are no getter/setter methods. Some of the codes cannot be compiled from Eclipse because of that.
If there are some special way to compile and run the code, please document it in a Readme file.

I will definitely buy this new edition of Spring in Action in November.

Thanks so much.

Chapter 3 problem

I read until page 66. There was

Even though you’ve only developed a repository for ingredient data, you can fire up the Taco Cloud application at this point and visit the design page to see JdbcIngredientRepository in action. Go ahead ... give it a try.

I give it a try and I failed.

I was following everything from the book. I see that my issue is in DesignTacoController, but I don't know how to solve it yet

I'm coding in Intellij Ultimate 2018.3

The application.yml should be renamed into application.properties.
It should have this content:

spring.h2.console.enabled=true
spring.h2.console.path=/h2

#Datasource can points to any file name, in this case, we call it test.
spring.datasource.url=jdbc:h2:file:~/test
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

Chapter 1. What is the difference between th:src and src? (Thymeleaf related question)

I'm confusing with <img th:src="@{/images/TacoCloud.png}"/> from example in the book. It doesn't show me the image in browser (the image in project is located under recources/static/images using IntelijIDEA. So I changed to <img src="../static/images/TacoCloud.png"/>as mentioned here and in this case it works. But if I specify like <img th:src="@{../static/images/TacoCloud.png}"/> then no. Why it happens? Can someone explain me, please? Because as I understand all variants must be valid.

Also I've found the solution for IDE like Eclipse - link to file in the file system. But for Intelij IDEA it doesn't work, because IntelijIDEA doesn't have this feature.
Plugin for Thymeleaf is working by default and I have as in example:
xmlns:th="http://www.thymeleaf.org"

Fully replicated your code in Chapter 4, doesn't work

Switching to another course now. Regret buying this book. Example not practical enough. Plus so many errors and unmentioned errors.
Not professional.
