Spring 弹簧靴部分取代自动配置

我一直在探索SpringBoot（1.2.4）以使用H2和Jackson创建一个简单的RESTful存储库

与其他人一样，我注意到，默认情况下，@Id字段不在返回的Json中（如本问题所述：）

所以我想调整配置以包含它们

但我很难让这一切正常运作

基本实体类：

@Entity
public class Thing {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id; //I want this to appear in the RESTful JSON

    private String someInformation;

    protected Thing(){};

    public String getSomeInformation() { return someInformation; }

    public void setSomeInformation(String someInformation) { this.someInformation = someInformation; }

}

基本存储库界面：

public interface ThingRepository extends PagingAndSortingRepository<Thing, Long> {    
    List<Thing> findBySomeInformation(@Param("SomeInformation") String someInformation);
}

和我的配置类：

@Configuration
public class RepositoryRestMvcConfig extends SpringBootRepositoryRestMvcConfiguration {     
    @Override
    protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
        config.exposeIdsFor(Thing.class);
    }        
}

通过使用--debug（如中所述）运行Spring Boot，我可以看到我的配置已经找到，但似乎没有任何效果。

Jackson处理类上的getter/setter，而不是成员变量本身。因此，要确保id在JSON中，只需为其添加一个getter：

@Entity
public class Thing {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id; //I want this to appear in the RESTful JSON

    private String someInformation;

    protected Thing(){};

    //this is what is needed
    public long getId() { return id; }

    public String getSomeInformation() { return someInformation; }

    public void setSomeInformation(String someInformation) { this.someInformation = someInformation; }

}

为id属性添加getter/setter？如果添加getter和setter，它将起作用

@Entity
public class Thing {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id; //I want this to appear in the RESTful JSON

    private String someInformation;

    protected Thing(){};

    //this is what is needed
    public long getId() { return id; }

    public String getSomeInformation() { return someInformation; }

    public void setSomeInformation(String someInformation) { this.someInformation = someInformation; }

}
