Tomcat 7 spring boot 启动失败

Question

我有一个 spring-boot 应用程序（Tomcat 7，Jdk 1.8，maven）我尝试运行（它不是嵌入式 tomcat) 我遇到了几个问题，例如：

 Exception in thread "restartedMain" java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

    at org.springframework.boot.SpringApplication.run(SpringApplication.java:306)
    at ep.OWebApplicationInitializer.main(OWebApplicationInitializer.java:14)

怎么了？我的 class 主要：

@SpringBootApplication
public class OWebApplicationInitializer extends SpringBootServletInitializer  {
    public static void main(String[] args) {
        new SpringApplication(OWebApplicationInitializer.class).run(args);
    }

}

我的 pom 也是这样的 :

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

有人知道这个问题吗？

Answer 1

您可以重写 SpringBootServletInitializer 的配置：

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(OWebApplicationInitializer.class);
}

Answer 2

您在类路径上的依赖项版本不匹配。

<parent>
<groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

并使用Tomcat 8.
