Spring Boot Tutorial-Spring boot integrated mybatis (annotation configuration)

Previous article: Spring Boot Tutorial-Spring boot Integrated MyBatis (XML) describes the spring boot integration mybatis XML-based configuration, this article focuses on annotation mode configuration mybatis. Development Environment JDK 1.8 Maven 3.3 Spring Boot 1.5.8.RELEASE Mybatis 3.4.4 configuration

First introduce spring-boot-starter-parent:

    <!--Inherit defaults from Spring Boot--
    <parent>
        <groupid>org.springframework.boot</ groupid>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8. Release</version>
    </parent>

Add MyBatis dependency:

    <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--mybatis -<dependency> <groupId>org.mybatis.spring.boot</groupId> <artif Actid>mybatis-spring-boot-starter</artifactid> <version>1.3.1</version> </depe
            ndency> <!--db--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.connector.version}</ver
            sion> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> & Lt;/dependency> &Lt;/dependencies> 

Application.yml

Server:
  port:9000

Spring:
    DataSource:
       url:jdbc:mysql://localhost:3306/demo?useunicode=true &characterencoding=utf-8&zerodatetimebehavior=converttonull
       username:root
       password:root
       Driver-class-name:com.mysql.jdbc.driver

Mybatisconfiguration

Package springboot.tutorials.mybatis.annotation.config;
Import Com.alibaba.druid.pool.DruidDataSource;
Import Org.apache.ibatis.session.SqlSessionFactory;
Import Org.mybatis.spring.SqlSessionFactoryBean;
Import Org.mybatis.spring.annotation.MapperScan;
Import Org.springframework.beans.factory.annotation.Qualifier;
Import Org.springframework.beans.factory.annotation.Value;
Import Org.springframework.context.annotation.Bean;
Import org.springframework.context.annotation.Configuration;
Import Org.springframework.core.io.support.PathMatchingResourcePatternResolver;
Import Org.springframework.jdbc.datasource.DataSourceTransactionManager;

Import Javax.sql.DataSource; 
        /** * @author Ricky Fung */@Configuration @MapperScan (basepackages = "Springboot.tutorials.mybatis.annotation.mapper", Sqlsessionfactoryref = "Sqlsessionfactory") public class Mybatisconfiguration {static final String mapper_l

    ocation = "Classpath:mapper/*.xml"; @Value ("${spring.datasource.url}") PrivaTe String url;

    @Value ("${spring.datasource.username}") private String user;

    @Value ("${spring.datasource.password}") private String password;

    @Value ("${spring.datasource.driver-class-name}") Private String Driverclass; @Bean (name = "Sqlsessionfactory") public sqlsessionfactory sqlsessionfactory (@Qualifier ("DataSource") DataSource data Source) throws Exception {final Sqlsessionfactorybean Sqlsessionfactorybean = new Sqlsessionfactorybe
        An ();
        Sqlsessionfactorybean.setdatasource (DataSource); Sqlsessionfactorybean.setmapperlocations (New Pathmatchingresourcepatternresolver (). GetResources (MAPPER_LO
        cation));
    return Sqlsessionfactorybean.getobject (); } @Bean (name = "DataSource") public DataSource DataSource () {Druiddatasource DataSource = new Druiddatas
        Ource ();
        Datasource.setdriverclassname (Driverclass);
        Datasource.seturl (URL); Datasource.setusername (user);
        Datasource.setpassword (password);
    return dataSource; } @Bean (name = "TransactionManager") public Datasourcetransactionmanager TransactionManager () {return NE
    W Datasourcetransactionmanager (DataSource ());
 }
}

The MyBatis mapper classes and mapper files involved are recommended to be generated by Mybatis-generator from the start, simple and efficient.

Launch class App

Package springboot.tutorials.mybatis.annotation;

Import org.springframework.boot.SpringApplication;
Import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author Ricky Fung *
 *
@SpringBootApplication public
class App {public

    static void main ( String[] args) {
        springapplication.run (app.class, args);
    }
}
