Spring Data 不从依赖 JAR 中自动装配实体答案

【问题标题】：Spring Data Not Autowiring Entity from Dependency JARSpring Data 不从依赖 JAR 中自动装配实体
【发布时间】：2017-02-16 21:37:11
【问题描述】：

我有一个包含依赖项 JAR 的 WAR。 JAR 包含横切关注点，也是由我编写的。我正在使用 Spring 4.2.3 和 Spring-data-jpa 1.9.1，我的配置是基于注释的。我部署到 Wildfly 10.1.0。

JAR 编译良好，我将其安装到本地 Maven 存储库。在 WAR 中，JAR 作为依赖项包含在内。到目前为止一切顺利。

在 WAR 的 Spring Configuration 文件上，我导入 Spring Configuration JAR 文件。

现在，当我拥有正常的 Spring Bean（服务或组件）时，一切正常，Spring 找到并解决了我的 JAR 中的所有依赖项和 Spring Bean，然后我可以从我的 WAR 中的代码中调用它们。

但是，一旦我添加了一个存储库和一个实体，Spring 就找不到该实体，随后我的 WAR 编译但它没有部署。我必须注意，如果我将 JAR 代码直接放入我的 WAR 中，那么所有这些都有效。我想我缺少一个配置，但我不知道还能去哪里看。

任何帮助将不胜感激。下面的代码和堆栈跟踪：

在部署时，我收到以下错误： 创建名为“synapseRepo”的 bean 时出错：调用 init 方法失败；嵌套异常是 java.lang.IllegalArgumentException: Not an managed type: class hyphen.synapse.data.model.Role

因此，错误非常简单，但我不确定让 Spring 了解我的实体还缺少什么。

谢谢。

用于配置的 JAR 代码：

@Configuration
@ComponentScan("hyphen.synapse")
@EnableTransactionManagement
@EnableJpaRepositories("hyphen.synapse.data")
@PropertySource("classpath:application.properties")
public class SynapseApplicationConfig {
...
}

存储库的 JAR 代码：

package hyphen.synapse.data.repo;

import hyphen.synapse.data.model.*;
import org.springframework.data.repository.*;

public interface SynapseRepo extends CrudRepository<Role, Long> {

}

实体的 JAR 代码：

package hyphen.synapse.data.model;

import javax.persistence.*;

@Entity
@Table(name = "ROLE")
public class Role extends SynapseBaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    @Column(name = "NAME")
    private String name;


    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

用于配置的 WAR 代码：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories("hyphen.cmd.data")
@PropertySource("classpath:application.properties")
@Import(hyphen.synapse.app.config.SynapseApplicationConfig.class)
public class ApplicationConfig {
...
}

用于注入的 WAR 代码：

package hyphen.synapse.data.dao;

import ...;

@Service
public class SynapseDao {
    @Inject
    private SynapseRepo synapseRepo;

    @Inject
    private EmailService emailService;

顺便说一句，JAR 中也定义了 EmailService，它是正确自动装配的。

以下代码行导致错误：

public interface SynapseRepo extends CrudRepository<Role, Long> ...

Spring 无法自动装配实体，在本例中为角色。我也知道 Role 不包含任何 Spring 注释。但是，我在 WAR 中有完全相同的代码并且它工作正常，但是使用依赖项 JAR 中包含的代码从 WAR 调用它似乎有问题。

【问题讨论】：

如果在 SynapseRepo 接口中添加@Repository 会怎样？
试过了，结果一样。它实际上不是必需的，因为它扩展了一个扩展 Repository 的接口，因此继承了它。

标签： spring spring-data spring-data-jpa

【解决方案1】：

您的SynapseRepo 和CommandRepo 接口应该有@Repository 注释。

但是问题的根源在于您的 WAR 文件中有一个 JPA 配置，而您的 JAR 中有一个 JPA 配置。因为名称、属性文件等会导致 bean 相互覆盖。您将需要花时间使它们独一无二。您可以按照https://stackoverflow.com/a/19976132/724835的说明进行操作

【讨论】：

感谢您的回复。您能否详细说明第 1 点，我不确定您的意思。关于第 2 点，我已经尝试过了，但结果相同，尽管它不是必需的，因为它是通过扩展 CrudRepository 继承的。
更仔细地查看错误我更新了我的答案。
感谢 JustinKSU，我已尝试过您的建议，但错误仍然存在。我还从角色类声明中删除了“扩展 SynapseBaseEntity”。 SynapseBaseEntity 是一个实现 Serializable 的空类，但我还是把它删除了。唯一引用类 Role 的地方是 SynapseRepo： public interface SynapseRepo extends CrudRepository { } 再考虑
当我直接将它部署为 WAR 时，这个确切的 JAR 代码库可以工作。我很高兴我的代码库可供审查。我可以在此处以 zip 格式上传吗？
我不确定是什么问题。它看起来是正确的。如果你可以在 GitHub 上分享代码，我可以看得更深。
