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

Question

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然后 java -jar app.jar ，它显示关于 shiro 的 NoSuchBeanDefinitionException。

Error creating bean with name 'userRealm': Unsatisfied dependency expressed through field 'sysUserRepository'

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;
    // ...
}

Answer 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命令而不是来自 spring boot gradle 插件。

至于为什么发生这种情况，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。

一种可能性是实现 ISysUserRepository 的类未包含在您的代码中，而是来自不同的 jar，并且当您运行 gradle jar 时该 jar 不包括在内，因此 Spring 在启动时找不到它，因此 Spring 不知道如何将它的实例注入(inject)到您的 UserRealm 中。
