Question

似乎我错过了一些东西：自动注入数据源工作，但DataSourceTransactionManager的注入失败。

依赖关系：

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.2.1.RELEASE</version>
</parent>
<dependencies>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
    </dependency>
</dependencies>

代码：

@SpringBootApplication
public class MainApplication {

  @Autowired
  private DataSource dataSource;

  // this fails
  @Autowired
  private DataSourceTransactionManager transactionManager;

  public static void main(String... args) {
    SpringApplication.run(MainApplication.class, args);
  }
}

我预计DataSourceTransactionManagerAutoConfiguration会处理它，但它没有。有线索吗？

Spring Boot正在注册PlatformTransactionManager bean，而您正在尝试注入DataSourceTransactionManager。如果您将改为正确的课程，它将开箱即用：

@Autowired
private PlatformTransactionManager transactionManager;

spring-boot：自动配置事务管理器
