一个user对象，其属性只有密码一项有值，其余均为NULL;
web.xml

action的代码：

public class UserinfoAction extends ActionSupport{

	private Userinfo userinfo;
	private String jsonString;
	private UserinfoService userinfoService;
	

	public Userinfo getUserinfo() {
		return userinfo;
	}


	public void setUserinfo(Userinfo userinfo) {
		this.userinfo = userinfo;
	}


	public void setUserinfoService(UserinfoService userinfoService) {
		this.userinfoService = userinfoService;
	}


	public String getJsonString() {
		return jsonString;
	}


	public void setJsonString(String jsonString) {
		this.jsonString = jsonString;
	}


	public String addUserinfo()throws Exception{
		System.out.println("name:"+userinfo.getUName());
		try {
			boolean flag = userinfoService.saveUser(userinfo);
			if(flag){
				jsonString="true";
				
			}else {
				jsonString="false";
			}
		} catch (Exception e) {
			e.printStackTrace();
			jsonString="false";
		}
		return SUCCESS;
	}

}

火狐响应的信息：
{"jsonString":"false","userinfo":{"UAddress":null,"UCollects":null,"UEmail":null,"UFans":null,"UFollows":null,"UId":null,"UMobile":null,"UName":null,"UNickname":null,"UPhoto":null,"UPwd":"1 ","URegtime":null,"USex":null,"USignature":null,"UWeibos":null}}

应该是哪个保存用户的方法有问题，究竟是什么问题，你应该debug看看吧。

发现两个问题：
1.
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
listener配置应该写在struts的filter之前

2。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext*.xml</param-value>
</context-param>

applicationContext*.xml和你的spring的配置文件名称不一致
