Maven搭建SSM框架(Spring+SpringMVC+MyBatis)

一、概述：

　　Spring是一个轻量级开发框架，好比一个大工厂（容器），可以将所有对象的创建和依赖关系交给spring管理。

　　SpringMVC是一个基于mvc的web框架。spring mvc是spring框架的一个模块，springmvc和spring无需通过中间整合层进行整合。

　　MyBatis是一个持久层的框架，在使用上相比Hibernate更加灵活，可以控制sql的编写，使用 XML或注解进行相关的配置.

二、搭建好项目的运行环境（java环境，Maven，Mysql，Tomcat），所使用工具Eclipse。具体的环境搭建请自行搜一下资料。jdk1.8+tomcat8.5

三、开始搭建

　　首先看一下项目结构。controller，mapper，pojo，service

　　

　　1.创建数据库表user,添加一条测试数据

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_name` varchar(40) NOT NULL,
  `password` varchar(255) NOT NULL,
  `age` int(4) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
insert  into `user_t`(`id`,`user_name`,`password`,`age`) values (1,‘admin‘,‘123456‘,21)

　　2. pom.xml文件中的包依赖

　　4.pojo实体

package com.iris.pojo;

public class User {
    private Integer id;
    private String user_name;
    private String password;
    private Integer age;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getUser_name() {
        return user_name;
    }
    public void setUser_name(String user_name) {
        this.user_name = user_name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }

}

　　5.dao层mapper接口

package com.iris.mapper;
import java.util.List;
import com.iris.pojo.User;
public interface UserMapper {
    Boolean  addUser(User user);
    Boolean  delUser(Integer id);
    Boolean  modUser(User user);
    List<User>  getUserList();
    User  getUserById(Integer id);
}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.iris.mapper.UserMapper">
      <select id="getUserList" resultType="com.iris.pojo.User">
          select * from user
      </select>
    <select id="getUserById" resultType="com.iris.pojo.User" parameterType="int">
          select * from user t where t.id=#{id}
      </select>
</mapper>

　　6.controller控制层,这里将返回数据类型统一封装到ResultBean

package com.iris.controller;

import java.io.Serializable;

import org.springframework.web.bind.annotation.RestController;
@RestController
public class ResultBean<T>  implements Serializable{
    private static final long serialVersionUID=1L;
    private static final int NO_LOGIN=-1;
    private static final int SUCCESS=0;
    private static final int FAIL=1;
    private static final int NO_PERMISSION=2;
    private String msg="success";
    private int code=SUCCESS;
    private T data;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public ResultBean() {
        super();
    }

    public ResultBean(T data) {
        super();
        this.data=data;
    }

    public ResultBean(Throwable e) {
        super();
        this.msg=e.toString();
        this.code=FAIL;
    }

}
package com.iris.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.iris.pojo.User;
import com.iris.service.UserService;
@RestController
public class UserController {
    @Autowired
    private UserService userService;
    @RequestMapping("/add")
    public ResultBean<Boolean> addUser(User user){
        return new ResultBean<Boolean>(userService.addUser(user));
    }
    @RequestMapping("/del")
    public ResultBean<Boolean> delUser(Integer id){
        return new ResultBean<Boolean>(userService.delUser(id));
    }
    @RequestMapping("/mod")
    public ResultBean<Boolean> modUser(User user){
        return new ResultBean<Boolean>(userService.modUser(user));
    }
    @RequestMapping("/getAll")
    public ResultBean<List<User>> getUserList(){
        return new ResultBean<List<User>>(userService.getUserList());
    }
    @RequestMapping("/getUser")
    public ResultBean<User> getUserById(Integer id){
        return new ResultBean<User>(userService.getUserById(id));
    }
}

　　7.service服务接口以及实现类

package com.iris.service;
import java.util.List;
import com.iris.pojo.User;
public interface UserService {
    Boolean  addUser(User user);
    Boolean  delUser(Integer id);
    Boolean  modUser(User user);
    List<User>  getUserList();
    User  getUserById(Integer id);
}
package com.iris.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.iris.mapper.UserMapper;
import com.iris.pojo.User;
import com.iris.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService{

    @Autowired
    private UserMapper userMapper;

    public Boolean addUser(User user) {
        return userMapper.addUser(user);
    }

    public Boolean delUser(Integer id) {
        return userMapper.delUser(id);
    }

    public Boolean modUser(User user) {
        return userMapper.modUser(user);
    }

    public User getUserById(Integer id) {
        return userMapper.getUserById(id);
    }

    public List<User> getUserList() {
        return userMapper.getUserList();
    }

}

以上只是一个小白查阅了相关资料做的一个总结，如有问题敬请指正。

一:概述 SSM框架在项目开发中经常使用到,相比于SSH框架,它在仅几年的开发中运用的更加广泛. Spring作为一个轻量级的框架,有很多的拓展功能,最主要的我们一般项目使用的就是IOC和AOP. SpringMVC是Spring实现的一个Web层,相当于Struts的框架,但是比Struts更加灵活和强大! Mybatis是 一个持久层的框架,在使用上相比Hibernate更加灵活,可以控制sql的编写,使用 XML或注解进行相关的配置! 根据上面的描述,学习SSM框架就非常的重要了! 二:搭

eclipse 搭建ssm （Spring+SpringMVC+MyBatis）

eclipse 开发软件搭建简单 ssm 开源框架并连接MySQL查询 前提:准备好搭建框架的jar.连接数据库的jar.日志架包jar和tomcat 不多说 我们开始 首先 创建项目File ->New-> Dynamic Web Project (名字随便起 我这里就起 ssm ) 在src下创建基本的包 导入jar的包 将jar包放进 WebContent ->web-INF ->lib里 (?? 一大堆 不知道哪个没有用  放进去就对了) jar包 链接:https://p

多工程：基于Maven的SSM（Spring,SpringMvc,Mybatis）整合的web工程(中)

上篇用了单工程创建了SSM整合的web工程(http://www.cnblogs.com/yuanjava/p/6748956.html),这次我们把上篇的单工程改造成为多模块工程 一:创建对应的多工程 首先原工程有对应的包如下 因为原单工程是 contoller 调用 service ,service 调用 mapper ,mapper 调用pojo 因此把对应的 service  mapper  pojo 分别拆分出去当做模块  然后把utils公用的抽出去当做common模块 最后创建出来

详解intellij idea搭建SSM框架(spring+maven+mybatis+mysql+junit)(上)

SSM(Spring+SpringMVC+MyBatis)框架集由Spring.SpringMVC.MyBatis三个开源框架整合而成,常作为数据源较简单的web项目的框架. 其中spring是一个轻量级的控制反转(IoC)和面向切面(AOP)的容器框架. SpringMVC分离了控制器.模型对象.分派器以及处理程序对象的角色,这种分离让它们更容易进行定制. MyBatis是一个支持普通SQL查询,存储过程和高级映射的优秀持久层框架. 本文旨在快速且详细的介绍intellij idea 搭建SS

使用maven搭建ssm框架的javaweb项目

目前主流的javawe项目,常会用到ssm(Spring+Spring MVC+Mybatis)框架来搭建项目的主体框架,本篇介绍搭建SSM矿建的maven项目的实施流程.记之共享! 一.SSM框架介绍 SSM框架是指:Spring+Spring MVC+Mybatis. [Spring] 轻量--从大小与开销两方面而言Spring都是轻量的,此外,Spring是非侵入式的:典型地,Spring应用中的对象不依赖于Spring的特定类.简单说就是自己需要什么就导入对应的jar的即可,而不是侵入式
