Struts2+spring3+mybatis3整合注解开发

这是myeclipse工程目录结构

接下来先web.xml

applicationcontext.xml

mybatis-config,xml

struts.xml

下面是代码
package com.action;
import org.springframework.beans.factory.annotation.Autowired;
import com.entity.SnUser;
import com.opensymphony.xwork2.ActionSupport;
import com.service.SnUserService;
import org.apache.struts2.convention.annotation.Action;  
import org.apache.struts2.convention.annotation.Result;  
@Action(value = "snUserAction", results = {  
        @Result(name = "saveok", location = "/suning_login.html"),
        @Result(name = "loginok", location= "/suning_main.html"),
        @Result(name = "loginno", params="shibai", location= "/suning_login.html")})  
public class SnUserAction extends ActionSupport{
private SnUserService snUserService;
@Autowired
public void setSnUserService(SnUserService snUserService) {
    this.snUserService = snUserService;
}
private SnUser snUser;
public SnUser getSnUser() {
    return snUser;
}
public void setSnUser(SnUser snUser) {
    this.snUser = snUser;
}
public String save(){
        snUserService.save(snUser);    
    return "saveok";
}
public String login(){
boolean flag=snUserService.login(snUser);
if(flag){
    return "loginok";
}else {
    return "loginno";
}
}
}

package com.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.dao.imp.SnUserDAO;
import com.entity.SnUser;
@Service
public class SnUserService {
private SnUserDAO snUserDAO;
@Autowired
public void setSnUserDAO(SnUserDAO snUserDAO) {
    this.snUserDAO = snUserDAO;
}
//注册
public void save(SnUser snUser){
    snUserDAO.save(snUser);    
}
//登录
public boolean login(SnUser snUser){
    SnUser user=snUserDAO.getUserByName(snUser.getUsername());
    if(user!=null){
        if(snUser.getPassword().equals(user.getPassword())){
            return true;
        }else {
            return false;
        }
    }else {
        return false;
    }
    
}
}

package com.entity;

import java.io.Serializable;

public class SnUser implements Serializable{
private Integer uid;
private String username;
private String password;
public Integer getUid() {
    return uid;
}
public void setUid(Integer uid) {
    this.uid = uid;
}
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;
}

}

package com.dao.imp;

import org.springframework.stereotype.Repository;

import com.entity.SnUser;
@Repository("snUserDAO")

public void update(SnUser snUser);
public void delete(int uid);
public SnUser getUserById(int uid);
public List<SnUser> getUserList();
public SnUser getUserByName(String username);
}
下面是新增页面的jsp
 <s:form action="snUserAction!save" method="post">
  <s:textfield label="USERNAME" name="snUser.username"/>
  <s:password label="PASSWORD" name="snUser.password"/>
    <s:submit value="新增"/>
    </s:form>
