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
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.iris</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>4.0.5.RELEASE</spring.version> <mybatis.version>3.2.1</mybatis.version> <log4j.version>1.2.12</log4j.version> <mysql.version>5.1.35</mysql.version> <shiro.version>1.2.4</shiro.version> </properties> <dependencies> <!-- 添加Spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!--spring单元测试依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!-- spring webmvc相关jar --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <!-- mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!-- alibaba data source 相关jar包--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>0.2.23</version> </dependency> <!-- alibaba fastjson 格式化对 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.5</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-asl</artifactId> <version>1.9.13</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- logback start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!--mybatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- 添加servlet3.0核心包 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.2-b01</version> </dependency> <!-- jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--单元测试依赖 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <finalName>ssm</finalName> </build> </project>
3.配置文件包括
jdbc,properties
jdbc.driver=com.mysql.jdbc.driver jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=UTF-8 jdbc.username=root jdbc.password=123456

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。
