二、编写配置文件

编写Spring的配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans
        xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:p="http://www.springframework.org/schema/p"
        xmlns:tx="http://www.springframework.org/schema/tx"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- 扫描注解,注册bean -->
    <context:component-scan base-package="com.kszsa">
        <!-- 跳过@Controller -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
</beans>

springMVC的配置文件 spring-mvc.xml

           http://cxf.apache.org/schemas/jaxws.xsd">

    <!-- mvc注解 -->
    <mvc:annotation-driven/>

    <!-- 扫描 -->

        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <!-- 开启事务注解 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>


</beans>

编写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>

    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- spring end -->

    <!-- spring mvc start -->
    <servlet>
        <servlet-name>spring-mvc</servlet-name>

        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- spring mvc end -->


</web-app>

至此配置文件编写完成

三、编写bean

编写User.java

package com.kszsa.user;

import javax.persistence.*;

@Entity
@Table(name="user")
public class User {
    @Id
    @Column(name="id")
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;

    @Column(name="name")
    private String name;

    @Column(name="description")
    private String description;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}

四、编写 DAO

编写通用接口ICommonDao.java

package com.kszsa.common.dao;

import java.io.Serializable;
import java.util.List;

public interface ICommonDao<T,PK extends Serializable> {

    T load(PK id);

    T get(PK id);

    List<T> findAll();

    void persist(T entity);

    void add(T entity);

    void update(T entity);

    void delete(PK id);

    void flush();


}

编写UserDao.java

package com.kszsa.user.dao;

import com.kszsa.common.dao.ICommonDao;
import com.kszsa.user.User;


public interface UserDao extends ICommonDao<User, Integer> {

}

编写UserDao实现类 UserDaoImp.java

package com.kszsa.user.dao;

import com.kszsa.user.User;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public class UserDaoImp implements UserDao {

    @Autowired
    private SessionFactory sessionFactory;

    private Session getSession() {
        return this.sessionFactory.getCurrentSession();
    }
    @Override
    public User load(Integer id) {
        return (User)this.getSession().load(User.class,id);
    }

    @Override
    public User get(Integer id) {
        return (User) this.getSession().get(User.class, id);
    }

    @Override
    public List<User> findAll() {
        return this.getSession().createQuery("from User").list();
    }

    @Override
    public void persist(User entity) {
        this.getSession().persist(entity);
    }

    @Override
    public void add(User entity) {
        this.getSession().save(entity);
    }

    @Override
    public void update(User entity) {
        this.getSession().update(entity);
    }

    @Override
    public void delete(Integer id) {
        User user = this.get(id);
        try{
            this.getSession().delete(user);
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    @Override
    public void flush() {
        this.getSession().flush();
    }
}

五、编写service层

编写UserService.java

package com.kszsa.user.service;

import com.kszsa.user.User;
import com.kszsa.user.dao.UserDaoImp;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Transactional
@Service
public class UserService {
    public void show(){
        System.out.println("userService is called...");
    }
    @Autowired
    private UserDaoImp userDaoImp;

    public User getById(Integer id) {
        return this.userDaoImp.get(id);
    }

    public List<User> findAll() {
        return this.userDaoImp.findAll();
    }

    public void add(User user) {
        this.userDaoImp.add(user);
    }

    public void update(User user) {
        this.userDaoImp.update(user);
    }
    public void delete(Integer id) {
        this.userDaoImp.delete(id);
    }
}

六、编写controller层

编写UserController.java

package com.kszsa.user.controllor;

import com.alibaba.fastjson.JSONObject;
import com.kszsa.user.User;
import com.kszsa.user.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/user")
public class UserControllor {

    @Autowired
    private UserService userService;

    @RequestMapping("hello")
    @ResponseBody
    public String hello(String name){
        userService.show();
        return "hello12345,"+name;
    }
    @RequestMapping("ceshi")
    public String ceshi(){
        return "ceshi";
    }

    @RequestMapping("add")
    @ResponseBody
    public String add(User user){
        String result = "successs";
        userService.add(user);
        return result;
    }

    @RequestMapping("delete")
    @ResponseBody
    public JSONObject delete(Integer id){
        JSONObject jsonObject = new JSONObject();
        Boolean success = true;
        String message = "删除用户成功";
        try {
            userService.delete(id);
        }catch (Exception e){
            success = true;
            message = "删除用户异常,异常信息"+e.getMessage();
        }
        jsonObject.put("success",success);
        jsonObject.put("message",message);
        return jsonObject;
    }

    @RequestMapping("update")
    @ResponseBody
    public JSONObject update(User user){
        JSONObject jsonObject = new JSONObject();
        Boolean success = true;
        String message = "更新用户成功";
        try {
            userService.update(user);
        }catch (Exception e){
            success = true;
            message = "更新用户异常,异常信息"+e.getMessage();
        }
        jsonObject.put("success",success);
        jsonObject.put("message",message);
        return jsonObject;
    }
    @RequestMapping("get")
    @ResponseBody
    public User get(Integer id){
        return userService.getById(id);
    }

}

七、编写前台页面

在webapp目录下,编写首页index.jsp

<html>
<body>
<h2>Hello World!</h2>
</body>
</html>

在webapp/WEB-INF/目录下,新建ceshi.jsp

<html>
<head>
    <title>Title</title>
</head>
<body>
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
</body>
</html>

至此,所有代码编写完成。

八、运行及接口测试

访问首页:http://localhost:8080/ssht/index.jsp

 访问测试页面:http://localhost:8080/ssht/user/ceshi

 访问hello,name的rest接口http://localhost:8080/ssht/user/hello?name=xiaodu

 访问用户添加页面:http://localhost:8080/ssht/user/add?name=libai&description=shiren

去数据库中查询新增的记录 

访问查询用户页面:http://localhost:8080/ssht/user/get?id=6

 访问删除用户界面:http://localhost:8080/ssht/user/delete?id=6

 到数据库中,查询,发现记录已经删除
