无法在传统的tomcat上运行我的SpringBoot项目

Question

我们有两个project1(usermgmt)和project2(instrumentsetup). SpringBoot项目由于我们需要在project1中使用project2中的服务和实体，我们将project1打包为 jar ，并在project2 (war)-root目录的'lib‘文件夹下添加了project1 jar。

在pom.xml of project2中，在“依赖”和“插件”下面添加了相同的内容。

<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>

我们主要的project2类包含以下内容：

com.xyz.usermgmt

-- project1包

com.xyz.instrumentsetup

- project2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，这个场景在嵌入式tomcat上运行得很好，但是对传统的tomcat却不起作用。我们使用project2 STS-4创建了war，并尝试在Tomcat8.0中部署该war。我们的jdk版本- jdk1.8.0_201

希望有人能指导我们解决这个问题。提前感谢

Answer 1

您使用的是哪个版本的spring引导？最新版本需要tomcat 9。

Answer 2

如果您正在使用<artifactId>spring-boot-starter-tomcat</artifactId>，并且希望在传统的Tomcat上部署应用程序，则必须在pom.xml的build部分告诉您使用提供的Tomcat (<scope>provided</scope>)。查看一下用于我的解决方案的这里或用于传统部署的Spring的这里。

我可能错了，因为这是我第一次看到问题来自未知的类引用。
