我正在尝试使用 Spring Data Rest 构建一个 Rest Api，在多次更改我的 pom.xml 以找到我的项目的兼容依赖项之后，我现在遇到了这个问题:
java.lang.AbstractMethodError: org.springframework.data.repository.core.support.RepositoryFactorySupport.getTargetRepository(Lorg/springframework/data/repository/core/RepositoryInformation;)Ljava/lang/Object;
从前...
我有一个 Java Config Web App，我的 JPAConfig 有这些注解
@Configuration
//@EnableJpaRepositories("com.protect.inf.jpa.repositories")
@EnableJpaRepositories
@EnableTransactionManagement
public class JPAConfig { ... }
查看 @EnableJpaRepositories 注释，如果我没有设置我的 Repositories 类的包名，应用程序启动正常，但是当我向 api 发出请求时，响应看起来像这个:
{
_links: {
profile: {
href: "http://localhost:8080/protect-inf-01/api/profile"
}-
}-
}
它不会暴露我的 Repos url。我的 Repos 类看起来像这样
@RestResource(path = "users", rel = "users")
public interface UsuariosRepository extends PagingAndSortingRepository<Usuarios, Integer>{
Usuarios findByEmail(String email);
}
然后...
当我将包名称设置为 @EnableRepositories 注释 @EnableJpaRepositories("com.protect.inf.jpa.repositories") 应用程序启动失败并出现此错误:
Error creating bean with name 'cuentasRepository': Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.springframework.data.repository.core.support.RepositoryFactorySupport.getTargetRepository(Lorg/springframework/data/repository/core/RepositoryInformation;)Ljava/lang/Object;
我认为这是我的 Maven 中的依赖问题，我不太确定。 这是我的 pom.xm

}
这是我的 WebConfiguration 类

import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;
@Configuration
public class WebConfiguration extends RepositoryRestMvcConfiguration{
@Override
public RepositoryRestConfiguration config() {
RepositoryRestConfiguration config = super.config();
config.setBasePath("/api");
return config;
}
}
欢迎任何帮助，谢谢!
已解决
删除 spring-data-commons 并将 spring-data-jpa 版本更改为 1.9.0.RELEASE 就像@peeskillet 所说的现在工作正常!
注释 spring-data-commons 依赖
<!-- <dependency> -->
<!-- <groupId>org.springframework.data</groupId> -->
<!-- <artifactId>spring-data-commons</artifactId> -->
<!-- <version>1.11.0.RC1</version> -->
<!-- </dependency> -->
更改 spring-data-jpa 版本
<!-- <dependency> -->
<!-- <groupId>org.springframework.data</groupId> -->
<!-- <artifactId>spring-data-jpa</artifactId> -->
<!-- <version>1.8.2.RELEASE</version> -->
<!-- </dependency> -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.9.0.RELEASE</version>
</dependency>
谢谢peeskillet!
最佳答案
摆脱 spring-data-commons 并将 spring-data-jpa 版本更改为 1.9.0.RELEASE。
spring-data-rest-webmvc 和 spring-data-jpa 都已经依赖于 spring-data-commons。但是您需要确保它们都依赖于相同的版本。 s-d-rest-webmvc-2.4.0 依赖于 s-d-commons-1.11.0 而 s-d-jpa-1.8.2 依赖于 s-d-commons-1.10.2。这就是区别。 s-d-jpa-1.9.0 依赖于 s-d-commons-1.11.0。
