service怎么注入到action

[HappyKeKe]

刚学这个，看书上的例子，很简单的，就试着做了，貌似这个书问题很多，现在贴出代码，望各位大侠帮忙看看

MyService.java

package han.service;

public interface MyService 
{
	boolean valid(String username,String password);
}

MyServiceImpl.java

package han.service.impl;

import han.service.MyService;

public class MyServiceImpl implements MyService
{
	public boolean valid(String username,String password)
	{
		if(username.equals("scott") && password.equals("tiger"))
		{
			return true;
		}
		else
			return false;
	}
}

LoginAction.java

package han.action;

import han.service.MyService;

import com.opensymphony.xwork2.Action;

public class LoginAction implements Action
{
	private String username;
	private String password;
	private MyService ms;
	private String tip;
	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 MyService getMs() {
		return ms;
	}
	public void setMs(MyService ms) {
		this.ms = ms;
	}
	public String getTip() {
		return tip;
	}
	public void setTip(String tip) {
		this.tip = tip;
	}
	public String execute() throws Exception
	{
		if(ms == null)
			System.out.println("ms is null");
		
		System.out.println(getUsername() + ", " + getPassword());
		if(ms.valid(getUsername(), getPassword()))
		{
			setTip("整合成功!");
			return SUCCESS;
		}
		return ERROR;
		
	}
}

现在的问题是action里的ms属性是null，是否还有什么没配置？？？
网上搜了很久，貌似都不对，刚学这个，很多不懂

<!DOCTYPE struts PUBLIC

你要加一句才行。表示action的对象由spring来创建

[仲兴轩]

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


好像是写在所有的之前吧,

[仲兴轩]

对咯,
你的action交由spring管理的话,
<action name="loginAction" class="loginAction">
<result name="error">/error.jsp</result>
<result name="success">/success.jsp</result>
</action>
你这里就直接写这个呀,不用再写类路径咯

这样的话 启动会报错

[HappyKeKe]

加了<constant name="struts.objectFactory" value="spring" />
和改了这个
<action name="loginAction" class="loginAction">
<result name="error">/error.jsp</result>
<result name="success">/success.jsp</result>
</action>
后 报这样的错

好像是写在所有的之前吧,

按这个来, 再改<action name="loginAction" class="loginAction">
这一行就应该不用加了--<constant name="struts.objectFactory" value="spring" />

[qianyecq]

有什么错误贴出来。

[HappyKeKe]

<context-param>

<param-value>/WEB-INF/applicationContext.xml</param-value>

这个放到前面了
<constant name="struts.objectFactory" value="spring" /> 这个也没加了
错误是

<package name="han.action" ----这里去掉han.?

感觉都对了呀,

[qianyecq]

把<package name="han.action" extends="struts-default">去了
加上下面这两句试试。
<constant name="struts.devMode" value="false" />
<package name="" extends="struts-default" namespace="/">

[HappyKeKe]

跟这个没关吧 没跟spring整一起都行的

你把tomcat从Program Files移到Program Files同一级，
然后在MyEclipse重新设置tomcat的路径，重新启动tomcat应该就可以了。

[HappyKeKe]

我错了 竟然忘了struts2-spring-plugin-2.1.6.jar包...
貌似<constant name="struts.objectFactory" value="spring" />这个不要也行啊
这个到底要不要呢

[仲兴轩]

真的弄好久,郁闷呀,

struts2整合spring要加struts2-spring-plugin-2.1.8.1.jar包,

[HappyKeKe]

恩啊 谢谢大家哈

[dxfly007]

我的出现类似的问题，也添加了struts2-spring-plugin-xxx.jar，但是问题照旧：
还请帮忙：
