我尝试在Spring启动环境中创建自定义存储库。所以我的所有存储库都可以通过扩展它来实现这种行为。
TestRepository.java
"projects": {
"YourCoolProject": {
"root": "",
...
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist",
...
"assets": [
"src/assets",
"myOtherStaticFiles" /* <-- Add *your* directory(s) here */
],
"styles": [
...
TestRepositoryImpl.java
@NoRepositoryBean
public interface TestRepository<T> extends JpaRepository<T, Long> {
Object getMemberValue(Long id, String memberName);
}
SampleRepository
public class TestRepositoryImpl<T> extends SimpleJpaRepository<T, Long> implements TestRepository<T> {
public TestRepositoryImpl(JpaEntityInformation<T, ?> entityInformation, EntityManager entityManager) {
super(entityInformation, entityManager);
}
@Override
public Object getMemberValue(Long id, String memberName) {
//logic to get member value
return null;
}
}
引导配置
@Repository
public interface UserRepository extends TestRepository<User> {
List<User> findByNameOrderById(String name);
}
但是应用程序无法启动并抛出异常。
@SpringBootApplication
@EnableJpaRepositories(repositoryBaseClass = TestRepositoryImpl.class)
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
&#13;
我是否缺少添加自定义存储库的任何配置?
更新
的pom.xml

Description:
Parameter 0 of constructor in com.test.repository.TestRepositoryImpl required a bean of type 'org.springframework.data.jpa.repository.support.JpaEntityInformation' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.data.jpa.repository.support.JpaEntityInformation' in your configuration.

附加pom.xml。 application.properties没有变化。
答案 0 :(得分:3)
看起来弹簧启动和弹簧数据的最新里程碑存在问题,如果切换回2.0.0.M1
一切正常:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.M1</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
将问题报告给Spring数据团队可能会更好。
