我们有两个 SpringBoot 项目project1(usermgmt) 和project2(instrumentsetup)。由于我们需要在项目2中使用project1中的服务和实体，我们将project1打包为jar，并将该项目1jar添加到project2(war)根目录的"lib"文件夹下。
在 project2 的 pom.xml 中，在"依赖项"和"插件"下方添加了相同的内容。
<dependency>
<groupId>com.xyz</groupId>
<artifactId>usermgmt</artifactId>
<version>1.0.0</version>
<!-- <scope>system</scope>
<systemPath>${basedir}/lib/usermgmt-1.0.0.jar</systemPath> -->
</dependency>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<id>install-external</id>
<phase>clean</phase>
<configuration>
<file>${basedir}/lib/usermgmt_1.jar</file>
<repositoryLayout>default</repositoryLayout>
<groupId>com.xyz</groupId>
<artifactId>usermgmt</artifactId>
<packaging>jar</packaging>
<version>1.0.0</version>
<generatePom>true</generatePom>
</configuration>
<goals>
<goal>install-file</goal>
</goals>
</execution>
</executions>
</plugin>
我们的 project2 主类包含以下内容：
com.xyz.usermgmt
-- 项目1包
com.xyz.instrumentsetup
---项目2
包@SpringBootApplication(scanBasePackages = {"com.xyz.usermgmt","com.xyz.instrumentsetup"})
@EntityScan({"com.xyz.usermgmt","com.xyz.instrumentsetup"})
@EnableJpaRepositories({"com.xyz.usermgmt","com.xyz.instrumentsetup"})
public class InstrumentsetupApplication extends SpringBootServletInitializer implements WebMvcConfigurer
{
private static final Logger log = LoggerFactory.getLogger(InstrumentsetupApplication.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(InstrumentsetupApplication.class).child(UsermgmtApplication.class).logStartupInfo(true);
}
public static void main(String[] args) {
log.info("Start of instrument setup");
ApplicationContext ctx = new SpringApplicationBuilder(InstrumentsetupApplication.class, UsermgmtApplication.class).run(args);
log.info("context created in instrument setup:" + ctx);
}
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE");
}
}
现在我们的问题是，这种情况适用于嵌入式雄猫，但不适用于传统的雄猫。 我们使用sts-4创建了project2的战争，并试图在tomcat 8.0中部署这场战争。 我们的 jdk 版本 -jdk1.8.0_201

希望有人可以指导我们解决问题。 提前
感谢苏巴希尼
您使用的是哪个版本的弹簧启动？最新版本需要 tomcat 9。
如果您使用的是<artifactId>spring-boot-starter-tomcat</artifactId>并且想要在传统的Tomcat上部署应用程序，则必须在pom.xml的build部分中告知使用提供的Tomcat(<scope>provided</scope>)。请在此处查看我的解决方案，或在此处查看用于传统部署的 Spring 文档。
我可能是错的，因为这是我第一次看到问题来自未知的类引用。
