SpringBoot特性随用随记

JDBC集成

pom依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

application.properties配置链接参数

spring.datasource.url=jdbc:mysql://localhost:3306/dbName?autoReconnect=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
spring.datasource.username=username
spring.datasource.password=******
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

    <artifactId>mybatis-spring-boot-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>

</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.3.2</version>

注解

@Mapper

@Options

@Select

@Insert

需要sqlSessionTemplate或sqlSessionFactory bean：

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
        sqlSessionFactory.setDataSource(dataSource);
        return (SqlSessionFactory) sqlSessionFactory.getObject();
    }

    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
      SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
      sqlSessionFactory.setDataSource(dataSource());
      return (SqlSessionFactory) sqlSessionFactory.getObject();
    }
