【超详细图文教程】用SpringBoot+Maven搭建SSM框架

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="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>demo</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.7.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.1</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

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;@Repositorypublic 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;@RestControllerpublic 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

spring.datasource.url=jdbc:mysql://localhost:3306/worldspring.datasource.username=rootspring.datasource.password=a8996855439spring.datasource.driverClassName=com.mysql.jdbc.Drivermybatis.type-aliases-package=com.example.models

最后运行DemoApplication，在地址栏输入http://localhost:8080/demo

结果如下，就成功了
