SSM框架整合
基于Maven+SpringMVC+Spring+MyBatis的组合，快速搭建SSM框架。适合初学者学习。
第一步：准备开发环境
JDK:1.8
Maven：apache-maven-3.6.0
Tomcat：apache-tomcat-8.5.41
(注：这些软件在此不再说明怎样安装，可以去问万能百度、谷歌等等)
第二步：添加Maven相关依赖

第三步：配置相关的配置
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
jdbc.username=root
jdbc.password=123456
######配置连接池#######
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000
mybatis：mybatis-config.xml配置如下
spring：applicationContext.xml配置如下
springmvc：spring-mvc.xml配置如下
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：创建sql语句
create table `t_student` (
`sid` int ,
`sno` varchar ,
`name` varchar ,
`sex` varchar
);
insert into `t_student` (`sid`, `sno`, `name`, `sex`) values('1','001','张三','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：编写pojo类
package com.xiaowen.model;
import java.io.Serializable;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
/**
* 学生实体类
* @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：编写mybatis映射文件
第七步：编写Dao数据层
package com.xiaowen.dao;
import java.util.List;
import com.xiaowen.model.Student;
public interface StudentMapper {
/**
* 查询所有学生信息
* @return
*/
List findAll();
}
第八步：编写service业务层及实现层
package com.xiaowen.service;
import java.util.List;
import com.xiaowen.model.Student;
public interface StudentService {
List 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 findAll() {
return studentMapper.findAll();
}
}
第九步：编写Controller控制层
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 findAll() {
List list=studentService.findAll();
return list;
}
第十步：启动Tomcat
浏览器访问:http://localhost:8080/ssmDemo/student/findAll.do,效果如下
