求助：整合struts和spring，applicationContext.xml报错

Question

struts和spring包都是直接添加MyEclipse 5.0 自带的，只在struts下测试成功
刚接触spring，对applicationContext.xml的bean的配置还不熟悉，下面的是测试代码：－－－－－－－－－－－
applicationContext.xml
------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans>

</bean>

<bean name="/login" class="cn.com.jac.dmps.user.action.LoginAction"

<bean id="userBo" class="cn.com.jac.dmps.user.bo.UserBO">
<property name="dao">
<ref bean="userDao" />
</property>
</bean>
</beans>

struts-config.xml

LoginAction.java:
---------------------------
package cn.com.jac.dmps.user.action;import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpSession;import org.apache.struts.action.Action;

    public void setUser(UserBO user) {
this.user = user;
    }

    public ActionForward execute(ActionMapping mapping, ctionForm form, HttpServletRequest request, HttpServletResponse response) {
       LoginForm loginForm = (LoginForm) form;
       String username = loginForm.getUsername();
       String password = loginForm.getPassword();
       ActionErrors errors = new ActionErrors();

       user.setUsername(username);
       user.queryByUsername(username);
       System.out.println(user.getPassword());
       return new ActionForward(mapping.getInput());
   }
}------------------------
UserBO.java
-------------------------package cn.com.jac.dmps.user.bo;import cn.com.jac.dmps.user.dao.UserDAO;public class UserBO implements IUserBO {
private int id;
private String username;

public void setDao(UserDAO dao) {
this.dao = dao;
} public int getId() {

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
} 

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public UserBO queryByUsername(String username) {
return dao.queryByUsername(username);
}
}

Answer 3

在创建userDao的时候出现了错误

Answer 4

userDao只有一个datasource字段，应该是datasource的问题

Answer 5

数据源的定义是继承自Spring的JdbcDaoSupport，用jdbcTemplate进行数据库操作
userDao还需要其他属性吗？
我的思路是通过loginForm输入的username传给UserBO，然后调用UserDAO中的queryByUsername(String username) 返回的UserBO对象
user和dao对象都由spring自动创建
按这样的顺序LoginAction<->UserBO<->UserDAO

Answer 6

struts-config.xml
中缺少配置
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation"
            value="/WEB-INF/applicationContext.xml,
                   /WEB-INF/action-servlet.xml"/>
    </plug-in>

Answer 7

是/WEB-INF/applicationContext.xml还是="/WEB-INF/classes/applicationContext.xml,看清楚啊！！

Answer 8

struts-config.xml 
中缺少配置 
<controller>
   <set-property property="processerClass" 
   value="org.springframework.web.struts.DelegatingRequestProcessor"/>
  </controller>
