This article focuses on "springboot integration mybatis example code", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn the "springboot integration mybatis example code" it!

In this section, let's talk in detail about how mybatis is integrated into the springboot environment.

1. Introduce mybatis related jar org.springframework.boot spring-boot-starter-web org.mybatis.spring.boot mybatis-spring-boot-starter 2.1.3 org.springframework.boot spring-boot-starter-jdbc 2.3.3.RELEASE mysql mysql-connector-java runtime org.projectlombok lombok true org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine 2. Configure mybatisserver: port: 8010spring: application: name: demo-mybatis# configure mysql database datasource: driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/lagou username: root password: rootmybatis:# specify the mapper xml file mapper-locations: classpath:mapping/*Mapper.xml# that needs to be loaded specify the package type-aliases-package: com.example.mybatis.pojo3. Startup class configuration annotation @ MapperScan, specify the mapper package file path @ SpringBootApplication@MapperScan (value = "com.example.mybatis.mapper") public class DemoMybatisApplication {public static void main (String [] args) {SpringApplication.run (DemoMybatisApplication.class, args);}} 4. Create a new User entity class (using lombok instead of the get set method) @ Data@ToStringpublic class User {private Integer id; private String username; private String password;} 5. Create a Mapper interface. Remember to add @ Repository annotation to the interface to indicate injection of spring@Repositorypublic interface IUserMapper {List getUserList (); User getUserById (Integer id); void addUser (User user); void updateUser (User user); void deleteUser (Integer id);} 6. Create the mapping file select * from users select * from users where id = # {id} insert into users values (# {id}, # {username}, # {password}) update users set username=# {username}, password= # {password} where id = # {id} delete from users where id = # {id} 7. Next, let's create a test class to test whether @ ExtendWith (SpringExtension.class) @ SpringBootTestclass IUserMapperTest {@ Autowired private IUserMapper userMapper; @ Test public void getUserList () {List userList = userMapper.getUserList (); for (User user: userList) {System.out.println (user) } @ Test void addUser () {User user = new User (); user.setId (3); user.setUsername ("lalala"); user.setPassword ("1qaz2wx"); userMapper.addUser (user);} @ Test public void getUserById () {User user = userMapper.getUserById (3); System.out.println (user) @ Test void updateUser () {User user = userMapper.getUserById (3); user.setUsername ("wudi"); userMapper.updateUser (user);} @ Test void deleteUser () {userMapper.deleteUser (3);}}

All right, now that my springboot has successfully integrated mybatis, we can use mybatis to handle our persistence layer business.

At this point, I believe that everyone has a deeper understanding of "springboot integration mybatis example code", might as well come to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
