SpringBoot搭建SSM
项目用Inteli做的，Eclipse的同学可以做参考
第一步：新建项目
第二步：配置pom.xml
-
xml version="1.0" encoding="UTF-8"?>
-
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-
xsi:schemaLocation=

第三步：创建数据库
第四步：创建目录
第五步：创建Student.java实体类
Student.java
-
package com.example.models;
-
-
public
class Student {
-
private
int id;
-
private String name;
-
private String sex;
-
private
int age;
-
-
public int getId() {
-
return id;
-
}
-
-
public void setId(int id) {
-
this.id = id;
-
}
-
-
public String getName() {
-
return name;
-
}
-
-
public void setName(String name) {
-
this.name = name;
-
}
-
-
public String getSex() {
-
return sex;
-
}
-
-
public void setSex(String sex) {
-
this.sex = sex;
-
}
-
-
public int getAge() {
-
return age;
-
}
-
-
public void setAge(int age) {
-
this.age = age;
-
}
-
-
@Override
-
public String toString() {
-
return
"Student{" +
-
"id=" + id +
-
", name='" + name +
'\'' +
-
", sex='" + sex +
'\'' +
-
", age=" + age +
-
'}';
-
}
-
}
第六步：创建Mapper接口
StudentMapper.java
-
package com.example.Dao;
-
-
import com.example.models.Student;
-
import org.apache.ibatis.annotations.Select;
-
import org.springframework.stereotype.Repository;
-
-
@Repository
-
public
interface StudentMapper {
-
@Select(
"SELECT * FROM student WHERE id=#{id}")
-
Student getStudentByID(int id);
-
}
第七步：创建Controller
StudentController.java
-
package com.example.Controller;
-
-
import com.example.Dao.StudentMapper;
-
import com.example.models.Student;
-
import org.springframework.beans.factory.annotation.Autowired;
-
import org.springframework.web.bind.annotation.RequestMapping;
-
import org.springframework.web.bind.annotation.RestController;
-
-
@RestController
-
public
class StudentController {
-
@Autowired
-
private StudentMapper studentMapper;
-
-
@RequestMapping(
"/demo")
-
public Student get(){
-
Student student=studentMapper.getStudentByID(
2);
-
return student;
-
}
-
-
@RequestMapping(value =
"res")
-
public String df(){
-
return
"Hello";
-
}
-
}
(注意这边新建接口对象的时候会出错误提示，但是不影响正常运行，原因不明，如果有哪位知道怎么解决请告知)
第八步：修改主程序
DemoApplication.java
-
package com.example.demo;
-
-
import org.mybatis.spring.annotation.MapperScan;
-
import org.springframework.boot.SpringApplication;
-
import org.springframework.boot.autoconfigure.SpringBootApplication;
-
import org.springframework.context.annotation.ComponentScan;
-
import org.springframework.transaction.annotation.EnableTransactionManagement;
-
-
@SpringBootApplication
-
@EnableTransactionManagement
-
@ComponentScan(
"com.example.Controller")
-
@MapperScan(
"com.example.Dao")
-
-
public
class DemoApplication {
-
-
public static void main(String[] args) {
-
SpringApplication.run(DemoApplication.class, args);
-
}
-
}
第九步：最后还有个SpringBoot的配置文件
application.properties
最后运行 DemoApplication，在地址栏输入http://localhost:8080/demo
结果如下，就成功了
