在 Spring boot gradle multiproject 中，gradlew bootRun 可以，但是运行生成的 jar 不行答案

【问题标题】：In Spring boot gradle multiproject, gradlew bootRun works, but running the generated jar does not在 Spring boot gradle multiproject 中，gradlew bootRun 可以，但是运行生成的 jar 不行
【发布时间】：2019-10-04 12:25:24
【问题描述】：

当我使用命令gradle bootRun 启动我的应用程序时，它按预期正常启动。但是，当我运行gradle build jar 和java -jar app.jar 时，它显示关于shiro 的NoSuchBeanDefinitionException。

创建名为“userRealm”的 bean 时出错：通过字段“sysUserRepository”表达的依赖关系不满足

我的应用程序是一个包含 bz-application 模块和 com-p2-infrastructuremodule 的 gradle 多项目。第二个包含实现 ISysUserRepository 所需的类。

这是我写的代码

public class UserRealm extends AuthorizingRealm {

    @Autowired
    ISysUserRepository sysUserRepository;
    @Autowired
    IUserRepository userRepository;
    // ...
}

【问题讨论】：

您确定您正在运行包含所有依赖项的jar吗？
可能相关：stackoverflow.com/questions/42458292，但问题可能并未显示所有详细信息。

标签： spring-boot gradle

【解决方案1】：

gradle jar 任务不会创建包含所有依赖项的可运行启动应用程序，它只会创建一个包含您自己的类的 jar。使用 gradle bootJar 命令代替 spring boot gradle 插件。

至于为什么会发生这种情况，您的问题没有包含足够的细节来准确地知道答案。您必须展示如何让 spring 检测到您的 bean。

一种可能是实现 ISysUserRepository 的类没有包含在您的代码中，而是来自不同的 jar，当您运行 gradle jar 时，该 jar 不包含在内，因此 Spring 在启动时找不到它，因此 Spring 没有知道如何将它的实例注入到您的 UserRealm 中。

【讨论】：

感谢您的回答。 ApplicationClass 中的组件扫描 @ComponentScan(basePackages= {"com.gwc.workday.*","com.pansome.*"}) 其他模块中的 ISysUserRepository com.pansome.infrastructure
我在运行 java -jar application\build\libs\bz-application-0.0.1-SNAPSHOT.jar 后使用 gradle bootJar 也是同样的异常。在 lib dir com-p2-infrastructure-0.0.1-SNAPSHOT.jar 中实现的 ISysUserRepository 我在 bz-application-0.0.1-SNAPSHOT.jar 的 bz-application-0.0.1-SNAPSHOT\BOOT-INF\lib 中看到跨度>
“在其他模块中”是什么意思？您可以将 jar 文件重命名为 ...zip 并查看文件内部包含的内容。然后检查它是否有应该用作bean的类。如果 jar 有它，那么原因一定在其他地方，可能需要发布你的 gradle 文件。
所以它是一个 gradle 多项目，有多个子模块？

【解决方案2】：

根据此错误报告： https://github.com/spring-projects/spring-boot/issues/6812

当您有两个模块被声明为应用程序时，您不能将其中一个模块用作另一个模块的库。

在您的情况下，com-p2-infrastructure 似乎不能既是可执行应用程序 jar 又是库 jar。可能它不应该是一个可执行的 spring boot 应用程序 jar，因为您想将其用作库模块，并使用 bz-application 作为应用程序。
