Question

亲爱的

我在尝试使用注释org.springframework.data.mongodb.repository.Query时遇到 java.lang.reflect.MalformedParameterizedTypeException ，并且我的Web应用程序无法在生产服务器上启动， 尽管测试服务器上具有相同WebSphere 9.0.0.8和JDK1.8的相同代码可以正常工作，请告知可能导致此问题的原因。

完整例外

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'registrationServiceImpl': Unsatisfied dependency expressed through field 'newRegistrationRepo'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'newRegistrationRepo': Cannot create inner bean '(inner bean)#e371922b' of type [org.springframework.data.repository.query.ExtensionAwareEvaluationContextProvider] while setting bean property 'evaluationContextProvider'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#e371922b': Initialization of bean failed; nested exception is java.lang.reflect.MalformedParameterizedTypeException
                at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:592)
                at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88)

这是我的java类中的注释

@Query("{'$and':[ {'cif':?0}, {'identification': ?1} , {'mobileNumber' : ?2}, {'applicationStatus' : 'Active' } ] }")

Answer 1

通过在查询中放置value属性来检查一次。

@Query(value="{'$and':[ {'cif':?0}, {'identification': ?1} , {'mobileNumber' : ?2}, {'applicationStatus' : 'Active' } ] }")

Answer 2

要使用@Query中的org.springframework.data.mongodb.repository.Query，必须添加以下依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

顺便说一句，很难弄清楚为什么它可以在测试服务器上工作

Answer 3

首先，@ Query来自导入org.springframework.data.mongodb.repository.Query;

您可以先尝试简单查询以检查配置问题。喜欢：

@Query("{ 'name' :  ?0 }")
@Query(value = "{ 'name' :  ?0 }", fields = "{ '_id': 0, 'name':1, 'age':1 }")

对于复杂的查询，您可以同时满足约定问题和“映射/解析数据”问题，请分步检查

更多内容：默认情况下，Mongo存储库通过AND查询，因此您的查询可以减少为：

'cif':?0, 'identification': ?1, 'mobileNumber' : ?2, 'applicationStatus' : 'Active'

Spring无法在Spring Data Mongodb中读取@query注释
