wiki中截图是在dubbo的jar包里面的，那改如何修改呢？

Could not publish to the server.
java.lang.IndexOutOfBoundsException

org.apache.http.impl.execchain.RetryExec 112 Retrying request to {}->http://127.0.0.1:8899

服务启动都正常，就是访问 http://127.0.0.1:8080/save 时候报／0的500，然后数据库还插入了mybatis_demo2一条数据。。。请问会是什么原因？

另外，我看这个demo模块里所有的service方法都没加TxTransaction注解，是不需要加吗（加了也没成功）

问题：jdbc版本的demo代码配置有问题；
问题描述：
1.applicationContext_db_mysql.xml中的lcnDataSourceProxy对象中并没有对应的dataSource成员变量，强制赋值，容器启动会提示（org.springframework.beans.NotWritablePropertyException: Invalid property 'dataSource' of bean class [com.codingapi.tx.datasource.relational.LCNTransactionDataSource]: Bean property 'dataSource' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?）
2.jdbcTemplate的dataSource成员变量赋值类型有问题，启动提示(java.lang.IllegalStateException: Cannot convert value of type 'com.codingapi.tx.datasource.relational.LCNTransactionDataSource' to required type 'javax.sql.DataSource' for property 'dataSource': no matching editors or conversion strategy found)
