（1）配置主 struts.xml 文件：

完整 src/struts.xml 文件请参见（附录1）。

（2）配置 src/user/struts.xml

<package name="userJson" extends="json-default">  <action name="getUser" class="user.action.getUser"> <result type="json" /> </action> </package>

完整 src/user/struts.xml 文件请参见（附录2）。

（3）配置 src/app-context.xml

<bean id="user.action.getUser" class="user.action.getUser" scope="prototype"> <property name="userService"> <ref bean="userServiceImpl"/> </property> </bean> <bean id="userServiceImpl" class="user.service.UserServiceImpl" scope="prototype"> <property name="userDao"> <ref bean="userDaoImpl"/> </property> </bean> <bean id="userDaoImpl" class="user.service.dao.UserDaoImpl" parent="daoTemplate.flm" scope="prototype"> </bean>

完整 src/app-context.xml 文件请参见（附录3）。

（4）配置 src/user/action/getUser.java

/** 用户 Service 接口. */ private UserService userService = null; public void setUserService(UserService userService) { this.userService = userService; } public UserService getUserService() { return userService; }

完整 src/user/action/getUser.java 文件请参见（附录4）。

（5）以下文件配置略去，请参见项目：NLMRPII 中的相应文件：

src/user/service/dao/UserDao.java

src/user/service/dao/UserDaoImpl.java

src/user/service/UserService.java

src/user/service/UserServiceImpl.java
