spring-data-rest发布的自定义jpa存储库方法 [英] Custom jpa repository method published by spring-data-rest
问题描述
我已经在jpa存储库中添加了一个自定义方法,详见 http://docs.spring.io/spring-data/data-jpa/docs/1.0.x/reference/html/#repositories.custom-implementations
I've added a custom method to a jpa repository as detailed on http://docs.spring.io/spring-data/data-jpa/docs/1.0.x/reference/html/#repositories.custom-implementations
据我所知,当我使用spring-data-rest时,这个方法不会暴露。有没有什么方法可以将它作为spring-data-rest生成的REST API的一部分发布(不用自己创建Spring MVC Controller)?
As far as I could see, this method is not exposed when I use spring-data-rest. Is there any way I could publish it as part of the REST API generated by spring-data-rest (without creating a Spring MVC Controller myself)?
推荐答案
我检查了代码库 - 似乎他们已经明确地禁用了自定义方法 - 不知道为什么。以下是org.springframework.data.repository.core.support.DefaultRepositoryInformation的相关代码。
I checked the code base - seems like they have explicitily disabled custom methods - not sure why. Here is the relevant piece of code from org.springframework.data.repository.core.support.DefaultRepositoryInformation
@Override
public Set<Method> getQueryMethods() {
Set<Method> result = new HashSet<Method>();
for (Method method : getRepositoryInterface().getMethods()) {
method = ClassUtils.getMostSpecificMethod(method, getRepositoryInterface());
if (isQueryMethodCandidate(method)) {
result.add(method);
}
}
return Collections.unmodifiableSet(result);
}
/**
* Checks whether the given method is a query method candidate.
*
* @param method
* @return
*/
private boolean isQueryMethodCandidate(Method method) {
return isQueryAnnotationPresentOn(method) || !isCustomMethod(method) && !isBaseClassMethod(method);
}
