SSM框架整合

基于Maven+SpringMVC+Spring+MyBatis的組合，快速搭建SSM框架。適合初學(xué)者學(xué)習。

第一步：準備開發(fā)環(huán)境
JDK:1.8
Maven：apache-maven-3.6.0
Tomcat：apache-tomcat-8.5.41
(注：這些軟件在此不再說明怎樣安裝，可以去問萬能百度沿腰、谷歌等等)

第二步：添加Maven相關(guān)依賴

        </dependency>
    </dependencies>
</project>

第三步：配置相關(guān)的配置

jdbc.properties：jdbc配置如下

######本地地址######
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8

    </aop:config>
    
   <!-- 自動掃描 -->
    <context:component-scan base-package="com.xiaowen.service" />
   
</beans>

springmvc：spring-mvc.xml配置如下

 <?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:p="http://www.springframework.org/schema/p"  
    xmlns:aop="http://www.springframework.org/schema/aop"   
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:jee="http://www.springframework.org/schema/jee"  
    xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="    
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
        http://www.springframework.org/schema/mvc   http://www.springframework.org/schema/mvc/spring-mvc.xsd

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">    

     
     <!-- 同時開啟json格式的支持 -->
    <mvc:annotation-driven/>
    
    <!-- 靜態(tài)資源 -->
    <mvc:resources mapping="/static/**" location="/static/"/>
    
    <!-- 視圖解析器 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp"></property>
    </bean>
    
    <context:component-scan base-package="com.xiaowen.controller" />
</beans>  

log4j：log4j.properties配置如下

 log4j.rootLogger=DEBUG, Console  
  
#Console  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  
  
log4j.logger.java.sql.ResultSet=INFO  
log4j.logger.org.apache=INFO  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG  

第四步：創(chuàng)建sql語句

create table `t_student` (
    `sid` int ,
    `sno` varchar ,
    `name` varchar ,
    `sex` varchar 
); 
insert into `t_student` (`sid`, `sno`, `name`, `sex`) values('1','001','張三','男');
insert into `t_student` (`sid`, `sno`, `name`, `sex`) values('2','002','李四','男');
insert into `t_student` (`sid`, `sno`, `name`, `sex`) values('3','003','王五','女');
insert into `t_student` (`sid`, `sno`, `name`, `sex`) values('4','004','周柳','女');

第五步：編寫pojo類

package com.xiaowen.model;

import java.io.Serializable;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

/**
  * 學(xué)生實體類
 * @author xiaowen
 *
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Student implements Serializable {
    private static final long serialVersionUID = 1L;
     private Integer sid;
     private String sno;
     private String name;
     private String sex;
}

第六步：編寫mybatis映射文件

<?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.xiaowen.dao.StudentMapper">
    
    <resultMap type="Student" id="StudentResult">
        <result property="sid" column="sid"/>
        <result property="sno" column="sno"/>
        <result property="name" column="name"/>
        <result property="sex" column="sex"/>
    </resultMap>
    
    <select id="findAll" resultType="Student" parameterType="map">
        select sid,sno,name,sex from t_student
    </select>
 

第七步：編寫Dao數(shù)據(jù)層

package com.xiaowen.dao;
import java.util.List;
import com.xiaowen.model.Student;

public interface StudentMapper {
    /**
     * 查詢所有學(xué)生信息
     * @return
     */
    List<Student> findAll();
}

第八步：編寫service業(yè)務(wù)層及實現(xiàn)層

package com.xiaowen.service;
import java.util.List;
import com.xiaowen.model.Student;
public interface StudentService {
    List<Student> findAll();
}

package com.xiaowen.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.xiaowen.dao.StudentMapper;
import com.xiaowen.model.Student;
import com.xiaowen.service.StudentService;
@Service
public class StudentServiceImp implements StudentService {
 
    @Autowired
    private StudentMapper studentMapper;

    public List<Student> findAll() {
        return studentMapper.findAll();
    }
}

第九步：編寫Controller控制層

package com.xiaowen.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.xiaowen.model.Student;
import com.xiaowen.service.StudentService;
@RestController
@RequestMapping("/student")
public class StudentController {

    @Autowired
    private StudentService studentService;

    @RequestMapping(value="/findAll")
    public List<Student> findAll() {
        List<Student> list=studentService.findAll();
        return list;
    }

第十步：啟動Tomcat
瀏覽器訪問:http://localhost:8080/ssmDemo/student/findAll.do,效果如下
