我正在尝试向 Spring 应用程序中的所有存储库添加自定义行为，但是我不想使用 XML 配置，只想使用 @xxxx 这样的 Spring 注释。
所以我在互联网上查找，发现this documentation 。 该文档的问题在于它涉及 JPA(而不是 MongoDB)，并且步骤 4 对于没有 xml 注释的 Spring 应用程序来说不够具体。
文档步骤 4:
declare beans of the custom factory directly
我们如何做到这一点？
所以我没有放弃，我在互联网上更深入地查找，我发现了this .
但这一次是针对 Solr(不是 Mongo)。 有趣的部分是:
import org.springframework.context.annotation.Configuration;
import org.springframework.data.solr.repository.config.EnableSolrRepositories;
@Configuration
@EnableSolrRepositories(
basePackages = "net.petrikainulainen.spring.datasolr.todo.repository.solr",
repositoryFactoryBeanClass = CustomSolrRepositoryFactoryBean.class
)
public class SolrContext {
//Configuration is omitted.
}
但是我的应用程序仍然无法运行!您可以在 github 中找到所有代码.
架构
src/main/java
fr.exemple.test.Application.java
fr.exemple.test.controller.TestController.java
fr.exemple.test.model.domain.Test.java
fr.exemple.test.model.repository.TestRepository.java
fr.exemple.test.model.repository.global.MyRepository.java
fr.exemple.test.model.repository.global.MyRepositoryFactoryBean.java
fr.exemple.test.model.repository.global.MyRepositoryImpl.java
我的代码
应用:
package fr.exemple.test;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import fr.exemple.test.model.repository.global.MyRepositoryFactoryBean;
@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableMongoRepositories(
basePackages = {"fr.exemple.test.repository.global"},
repositoryFactoryBeanClass = MyRepositoryFactoryBean.class
)
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.setShowBanner(false);
app.run(args);
}
}
测试 Controller :
package fr.exemple.test.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import fr.exemple.test.model.repository.TestRepository;
@RestController
@RequestMapping("/test")
public class TestController {
@Autowired
private TestRepository repository;
@RequestMapping(method=RequestMethod.GET)
public void sharedCustomMethodTest() {
repository.sharedCustomMethod("Hello World !");
}
}
测试:
package fr.exemple.test.model.domain;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document
public class Test {
@Id
private String id;
private String firstName;
private String lastName;
public Test() {}
public Test(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
@Override
public String toString() {
return String.format(
"Customer[id=%s, firstName='%s', lastName='%s']",
id, firstName, lastName);
}
}
测试存储库:
package fr.exemple.test.model.repository;
import fr.exemple.test.model.domain.Test;
import fr.exemple.test.model.repository.global.MyRepository;
public interface TestRepository extends MyRepository<Test, String> {
}
我的存储库:
package fr.exemple.test.model.repository.global;
import java.io.Serializable;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.repository.NoRepositoryBean;
@NoRepositoryBean
public interface MyRepository<T, ID extends Serializable> extends MongoRepository<T, ID>{
void sharedCustomMethod(ID id);
}
MyRepositoryFactoryBean:
package fr.exemple.test.model.repository.global;
import java.io.Serializable;
import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.core.mapping.BasicMongoPersistentEntity;

MongoPersistentEntity<T> pe = new BasicMongoPersistentEntity<T>(information);

return new MyRepositoryImpl<T, I>(mongometa, mongoOperations);
}
protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
return MyRepository.class;
}
}
}
MyRepositoryImpl:
package fr.exemple.test.model.repository.global;
import java.io.Serializable;

import org.apache.commons.logging.LogFactory;
import org.springframework.data.mongodb.core.MongoOperations;

private Log log = LogFactory.getLog(MyRepositoryImpl.class);
private MongoOperations mongoOperations;
public MyRepositoryImpl(MongoEntityInformation<T, ID> metadata,
MongoOperations mongoOperations) {
super(metadata, mongoOperations);
this.mongoOperations = mongoOperations;
}
@Override
public void sharedCustomMethod(ID id) {
log.info(id);
}

最佳答案
出现这种情况是因为包结构不一致。 @EnableMongoRepositories的基础包指向fr.exemple.test.repository.global而存储库定义位于 fr.exemple.test.model.repository 。当存储库扫描返回时没有任何结果引导自动配置，此时不知道任何自定义 RepositoryFactoryBean 定义，开始启动 fr.exemple.test 上的存储库哪里Application居住。
所以你可以更新你的包结构。
或者让引导知道MyRepositoryFactoryBean通过 @Component 在您的上下文中注册它并删除 @EnableMongoRepositories这样scanning for RepositoryFactoryBeanSupport 类型的 bean可以获取配置。
关于spring - 向所有存储库添加自定义行为，无需 xml 配置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24721536/
