ssh整合思想 Spring分模块开发 crud参数传递 解决HTTP Status 500 - Write operations are not allowed in read-only mode (FlushMode.MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or（增加事务）

在Spring核心配置文件中没有增加事务方法，导致以上问题

Action类UserAction

package com.swift.action;

import com.opensymphony.xwork2.ActionSupport;
import com.swift.service.UserService;

public class UserAction extends ActionSupport {
    private UserService userService;
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
    @Override
    public String execute() throws Exception {
        System.out.println("action..................");
        userService.add("fly","War of Mercenaries");
        userService.add("big-dog","War of Mercenaries");
        userService.add("ram","War of Mercenaries");
        userService.add("rabbit","War of Mercenaries");
        userService.add("hama","War of Mercenaries");
        userService.add("shiguan","War of Mercenaries");
        userService.update("ram","War of Mercenaries","公羊","佣兵的战争");
        userService.delete("rabbit","War of Mercenaries");
        userService.getOne(2);
        userService.findAll();
        userService.findYouWant("ram","War of Mercenaries");
        return NONE;
    }

}

UserService类

package com.swift.service;

import org.springframework.transaction.annotation.Transactional;

import com.swift.dao.UserDao;
@Transactional
public class UserService {

    private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    public void add(String userName,String address) {
        System.out.println("UserService.................add");
        userDao.add(userName,address);
    }
    public void update(String userName,String address,String modifyName,String modifyAddress) {
        System.out.println("UserService.................update");
        userDao.update(userName,address,modifyName,modifyAddress);
    }
    public void delete(String userName,String address) {
        System.out.println("UserService.................delete");
        userDao.delete(userName,address);
    }
    public void getOne(int number) {
        System.out.println("UserService.................get the number of");
        userDao.getOne(number);
    }
    public void findAll() {
        System.out.println("UserService.................find all");
        userDao.findAll();
    }
    public void findYouWant(String userName,String address) {
        System.out.println("UserService.................find you want");
        userDao.findYouWant(userName,address);
    }

}

UserDao接口

package com.swift.dao;

public interface UserDao {
    public void add(String userName,String address);
    public void update(String userName,String address,String modifyName,String modifyAddress);
    public void delete(String userName,String address);
    public void getOne(int number);
    public void findAll();
    public void findYouWant(String userName,String address);
}

UserDaoImplements类

package com.swift.dao;

import java.util.List;

import org.springframework.orm.hibernate5.HibernateTemplate;

import com.swift.entity.User;

public class UserDaoImplements implements UserDao {
    private HibernateTemplate hibernateTemplate;

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }

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

    @Override
    public void add(String userName, String address) {
        // 增加
        user.setUsername(userName);
        user.setAddress(address);
        hibernateTemplate.save(user);
    }

    @Override
    public void update(String userName, String address, String modifyName, String modifyAddress) {
        List<User> list = (List<User>) hibernateTemplate.find("from User where userName=? and address=?", userName,
                address);
        if (list != null) {
            for (User user : list) {
                System.out.println(user.getUsername() + " :: " + user.getAddress());
                user.setUsername(modifyName);
                user.setAddress(modifyAddress);
                hibernateTemplate.update(user);
            }
        } else {
            System.out.println("您要更新的记录不存在！！！！！");
        }
    }

    @Override
    public void delete(String userName, String address) {
        List<User> list = (List<User>) hibernateTemplate.find("from User where userName=? and address=?", userName,

                hibernateTemplate.delete(user);
            }
        } else {

        }
    }

    @Override
    public void getOne(int number) {
        User user = hibernateTemplate.get(User.class, number);
        System.out.println(user.getUsername() + " :: " + user.getAddress());
    }

    @Override
    public void findAll() {
        List<User> list = (List<User>) hibernateTemplate.find("from User");
        for (User user : list) {

        for (User user : list) {
            System.out.println(user.getUsername() + " :: " + user.getAddress());
        }
    }

}

User实体类：

package com.swift.entity;

public class User {

    private Integer uid;
    private String username;
    private String address;
    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 getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public User(String username, String address) {
        this.username = username;
        this.address = address;
    }
    public User(Integer uid, String username, String address) {
        this.uid = uid;
        this.username = username;
        this.address = address;
    }
    public User() {
        super();
        // TODO Auto-generated constructor stub
    }

}
