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

我已将自定义方法添加到 jpa 存储库中，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，这个方法在我使用 spring-data-rest 的时候没有暴露出来.有什么办法可以将它发布为 spring-data-rest 生成的 REST API 的一部分(无需自己创建 Spring MVC 控制器)?

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 - 似乎他们已经明确禁用了自定义方法 - 不知道为什么.这是来自 org.springframework.data.repository.core.support.DefaultRepositoryInformation

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);
}
