详解springboot中mybatis注解形式
在本文中小编给大家分享了关于springboot中mybatis注解形式的介绍，有兴趣的可以跟着学习下。springboot整合mybatis对数据库进行访问，本实例采用注解的方式，如下：
pom.xml文件
<parent>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-parent</artifactid>
<version>2.0.5.release</version>
</parent>
<properties>
<project.build.sourceencoding>utf-8</project.build.sourceencoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<dependencies>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-web</artifactid>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-test</artifactid>
<scope>test</scope>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-web</artifactid>
</dependency>
<dependency>
<groupid>mysql</groupid>
<artifactid>mysql-connector-java</artifactid>
<version>5.1.45</version>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-jdbc</artifactid>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-configuration-processor</artifactid>
<optional>true</optional>
</dependency>
<dependency>
<groupid>org.mybatis.spring.boot</groupid>
<artifactid>mybatis-spring-boot-starter</artifactid>
<version>1.3.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-maven-plugin</artifactid>
</plugin>
</plugins>
</build>
</project>
domain类
package com.rookie.bigdata.domain;
/**
* @author
* @date 2018/10/9
*/
public class student {
private long stuno;
private string name;
private integer age;
public student() {
}
public student(string name, integer age) {
this.name = name;
this.age = age;
}
public student(long stuno, string name, integer age) {
this.stuno = stuno;
this.name = name;
this.age = age;
}
public long getstuno() {
return stuno;
}
public void setstuno(long stuno) {
this.stuno = stuno;
}
public string getname() {
return name;
}
public void setname(string name) {
this.name = name;
}
public integer getage() {
return age;
}
public void setage(integer age) {
this.age = age;
}
@override
public boolean equals(object o) {
if (this == o) return true;
if (o == null || getclass() != o.getclass()) return false;
student student = (student) o;
if (stuno != null ? !stuno.equals(student.stuno) : student.stuno != null) return false;
if (name != null ? !name.equals(student.name) : student.name != null) return false;
return age != null ? age.equals(student.age) : student.age == null;
}
@override
public int hashcode() {
int result = stuno != null ? stuno.hashcode() : 0;
result = 31 * result + (name != null ? name.hashcode() : 0);
result = 31 * result + (age != null ? age.hashcode() : 0);
return result;
}
@override
public string tostring() {
return "student{" +
"stuno=" + stuno +
", name='" + name + '\'' +
", age=" + age +
'}';
}
}
studentmapper类
package com.rookie.bigdata.mapper;
import com.rookie.bigdata.domain.student;
import org.apache.ibatis.annotations.*;
import java.util.list;
import java.util.map;
/**
* @author
* @date 2018/10/9
*/
@mapper
public interface studentmapper {
@select("select * from student where name = #{name}")
student findbyname(@param("name") string name);
@results({
@result(property = "name", column = "name"),
@result(property = "age", column = "age")
})
@select("select name, age from student")
list<student> findall();
@insert("insert into student(name, age) values(#{name}, #{age})")
int insert(@param("name") string name, @param("age") integer age);
@update("update student set age=#{age} where name=#{name}")
void update(student student);
@delete("delete from student where id =#{id}")
void delete(long id);
@insert("insert into student(name, age) values(#{name}, #{age})")
int insertbyuser(student student);
@insert("insert into student(name, age) values(#{name,jdbctype=varchar}, #{age,jdbctype=integer})")
int insertbymap(map<string, object> map);
}
测试类如下：
package com.rookie.bigdata.mapper;
import org.junit.test;
import org.junit.runner.runwith;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.boot.test.context.springboottest;
import org.springframework.test.context.junit4.springrunner;
import org.springframework.transaction.annotation.transactional;
import static org.junit.assert.*;
/**
* @author
* @date 2018/10/10
*/
@runwith(springrunner.class)
@springboottest
public class studentmappertest {
@autowired
private studentmapper studentmapper;
@test
public void findbyname() throws exception {
system.out.println(studentmapper.findbyname("zhangsan"));
}
@test
public void findall() throws exception {
system.out.println(studentmapper.findbyname("zhangsan"));
}
@test
public void insert() throws exception {
system.out.println(studentmapper.insert("zhangsan", 20));
}
@test
public void update() throws exception {
}
@test
public void delete() throws exception {
}
@test
public void insertbyuser() throws exception {
}
@test
public void insertbymap() throws exception {
}
}
大家可以自己编写测试类进行测试一下，后续会更新xml的配置方式和mybatis采用多数据源进行配置的方式
