Spring Boot Tomcat容器部署错误

Question

我想将我的Spring Boot应用程序作为WAR部署到Tomcat容器，但Tomcat无法启动容器。我已经按照Spring Boot Reference中的文档Traditional Deployment Section进行了操作。容器的线程大小设置为-Xss 4068，但我仍然收到堆栈溢出错误。

这是堆栈跟踪：

我的pom.xml具有以下Spring Boot依赖关系， spring-boot-starter-tomcat 范围设置为提供，如文档中所述。

的pom.xml

    <!-- Spring Boot -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

        <artifactId>spring-security-config</artifactId>
        <version>${spring.security.version}</version>
    </dependency>

更新：其他pom依赖项：

<dependency>
   <groupId>com.ibm.db2</groupId>
   <artifactId>db2jcc4</artifactId>
   <version>9.7.0.9</version>
</dependency>
<dependency>
<groupId>com.ibm.db2</groupId>
   <artifactId>db2jcc_license</artifactId>
   <version>9.7.0.9</version>
</dependency>

我的主类扩展了SpringBootServletInitializer，如文档中所述：

CustomerSiteMain.java：

@Configuration
@ComponentScan("com.mydomain")
@EnableAutoConfiguration
public class CustomerMain extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
        return application
            .showBanner(true)
            .parent(Global.class)
            .sources(CustomerMain.class)
            .profiles("container");
    }

    public static void main(String[] args) {
        SpringApplication.run(CustomerMain.class, args);
    }

   @Bean
   @Profile(CustomerSiteProfiles.STANDALONE)
   public ServletRegistrationBean h2Console() {
      ServletRegistrationBean reg = new ServletRegistrationBean(new WebServlet(), "/console/*");
      reg.setLoadOnStartup(1);
      return reg;
   }

   @Bean
   public ServletRegistrationBean servletRegistrationBean(){
       return new ServletRegistrationBean(new PhotoSheetPDFServlet(), "/items/factsheet/*");
   }
}

以上也帮助了我。我有一个类似的问题，并继续得到这样的WebappClassLoader日志：

2015-03-06 20:32:53,741 org.apache.catalina.loader.WebappClassLoader   validateJarFile INFO: validateJarFile(/usr/local/apache-tomcat-7.0.54/webapps/gs-producing-web-service-0.1.0/WEB-INF/lib/tomcat-embed-core-8.0.15.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/servlet/Servlet.class
2015-03-06 20:32:53,742 org.apache.catalina.loader.WebappClassLoader validateJarFile INFO: validateJarFile(/usr/local/apache-tomcat-7.0.54/webapps/gs-producing-web-service-0.1.0/WEB-INF/lib/tomcat-embed-el-8.0.15.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/el/Expression.class

这是我在加载Web应用程序时遇到的这个严重错误的线索。

2015-03-06 20:32:54,704 org.apache.catalina.startup.HostConfig deployWAR SEVERE: Error deploying web application archive /usr/local/apache-tomcat-7.0.54/webapps/gs-producing-web-service-0.1.0.war

我在我的案例中开发了一个Web服务，并且在我的pom.xml中开发了这些依赖项（Web服务而不是web）

<dependencies>
    <!-- tag::springws[] -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-ws</artifactId>
    </dependency>
    <dependency>
        <groupId>wsdl4j</groupId>
        <artifactId>wsdl4j</artifactId>
    </dependency>
    <!-- end::springws[] -->
     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency> 
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency> 
</dependencies>

但是在maven安装之前我忘记了干净。这花了我几个小时，因为我的tomcat图书馆还在那里 用户小心您在按照https://spring.io/guides/gs/convert-jar-to-war/和http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

按键时应该对maven进行清理工作

现在这对于更快速的发展来说非常好。感谢

看起来你的Tomcat正在尝试加载一些已加载的类。 尝试从 spring-boot-starter-web 依赖

中排除嵌入式tomcat

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
