实体类

public class Person {
    private String id;
    private String name;
    private int age;
    private String sex;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Person{" +
                "id='" + id + '\'' +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }
}

Dao接口

public interface TestDao {
    void insertData(Person person);
}

xml

<?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.hkj.springbootmybatisdemo.dao.TestDao">
    <insert id="insertData" parameterType="com.hkj.springbootmybatisdemo.entity.Person">
        <selectKey keyProperty="id" order="BEFORE" resultType="java.lang.String">
            select replace(uuid(), '-', '') as id from dual
        </selectKey>
        insert into person(id,name,age,sex) values (#{id},#{name},#{age},#{sex})
    </insert>
</mapper>

在要做测试的类上生成测试方法，如测试ServiceTestImpl类

测试ServiceTestImpl

测试类

@RunWith(SpringRunner.class)
@SpringBootTest
public class ServiceTestImplTest {
    @Autowired
    private TestDao testDao;

    @Test
    @Transactional // 回滚，避免测试数据入库
    public void test2(){
        Person person = new Person();
        person.setName("王五");
        person.setAge(11);
        person.setSex("女");
        testDao.insertData(person);
        System.out.println(person.getId());
    }
}

若想生成自增主键，可采取下列写法，此时实体的id应为Integer类型

<insert id="insertExample" parameterType="实体">
        <selectKey keyProperty="id" order="AFTER" resultType="java.lang.Integer">
            select LAST_INSERT_ID()
        </selectKey>
        insert sql...
</insert>
