Question

我正在尝试使用Spring Data Rest构建Rest Api，在多次更改我的pom.xml以找到与我的项目兼容的依赖项之后，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;

曾几何时......

我有一个Java Config Web App，我的JPAConfig有这些注释

@Configuration
//@EnableJpaRepositories("com.protect.inf.jpa.repositories")
@EnableJpaRepositories
@EnableTransactionManagement
public class JPAConfig { ... }

请参阅@EnableJpaRepositories注释，如果我没有将软件包名称设置为我的Repositories类，则应用程序启动正常，但是当我向api发出请求时，响应如下所示：

{
_links: {
    profile: {
        href: "http://localhost:8080/protect-inf-01/api/profile"
        }-
    }-
}

它不会暴露我的Repos网址。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")时，应用程序启动失败，并显示以下错误：

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Maven中的依赖问题，我不太确定。这是我的pom.xm

    @Override

}

这是我的WebConfiguration班级

package com.protect.inf.config;

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！

解决正在删除spring-data-commons并将spring-data-jpa版本更改为1.9.0.RELEASE，就像@peeskillet说现在工作正常！

评论spring-data-commons依赖

更改spring-data-jpa版本

    </dependency>

谢谢peeskillet！

Answer 1

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都已依赖spring-data-commons。但是你需要确保它们都依赖于相同的版本。 s-d-rest-webmvc-2.4.0取决于s-d-commons-1.11.0而s-d-jpa-1.8.2取决于s-d-commons-1.10.2。这就是区别。 s-d-jpa-1.9.0取决于s-d-commons-1.11.0。
