mybatis-spring-boot-cant不能使用作为bean注入数据源

Question

下面是我的配置类。

@Configuration
@Component
class Config {
@Bean
@ConfigurationProperties(prefix = "my.spring.datasource")
public javax.sql.DataSource dataSource() {

    return DataSourceBuilder
            .create()
            .build();
}

}  

- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.type) did not find property 'spring.datasource.type'
- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
- Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'javax.transaction.TransactionManager'   

- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
- Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'javax.transaction.TransactionManager'

确保您已经在application.yml中配置了以下属性

spring:
  datasource:
    url: jdbc:oracle:thin:@db-host:port/catalog
    username: user
    password: pass
    driver-class-name: oracle.jdbc.OracleDriver

这样做之后，就可以将datasource注入到sping组件；如下所示。

@Autowired
DataSource dataSource;
