无法启动嵌入式容器;嵌套的例外是java.lang.NoSuchMethodError：javax.servlet.ServletContext.addServlet

问题描述 投票：1回答：3

这是我在运行测试：

@SpringBootApplication
@EnableSwagger2 
@ComponentScan(basePackages="com.tsinghua.controller,com.tsinghua.manager,com.tsinghua.facade")
public class App extends SpringBootServletInitializer implements      EmbeddedServletContainerCustomizer {

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

@Override  
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {  
    return builder.sources(App.class);  
}  
public void customize(ConfigurableEmbeddedServletContainer container) {  
    container.setPort(28090);  
}  

@Bean
public Docket mathApi() {
}


@Bean
public Docket serverApi() {
}

private Predicate<String> categoryPaths() {
    return regex("/math.*");
}

private ApiInfo apiInfo() {
}

private ApiInfo serverApiInfo() {
}
}

这是pom.xml中：

你有相当多的问题，在你的身材。首先，你靠spring-boot-starter-web（带来的Tomcat）和spring-boot-starter-jetty所以基本上你在你的应用程序两个嵌入式容器。

新人可能不知道的是，但经验法则是只加严格什么是必要的，看看会发生什么。如果您的应用程序只与web首发作品，那么它变得很明显，如果你添加的码头，你需要删除别的东西。这是covered in the documentation。

与servlet-api同样的事情。要导入自己。更糟的是，你强迫自己一个版本。你不应该这样做。春天启动配有一整套依赖管理。如果你开始覆盖那些有自己的选择，你有责任确保所有这些一起工作。他们显然不给出的堆栈跟踪。

卸下servlet-api依赖（它已经由web起动机提供）和固定码头的依赖。

我有同样的问题，当我使用码头嵌入式服务器，和我刚刚加入依赖Servlet API的，即解决我的问题：

Pom.hml：

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

我们有同样的问题，但只是偶尔，它是随机的：

无法启动嵌入式容器;嵌套异常是java.lang.NoSuchMethodError：javax.servlet.ServletContext.addServlet（Ljava /郎/字符串; Ljavax / servlet的/ Servlet的）Ljavax / servlet的/ ServletRegistration $动态;

我们还使用“弹簧引导起动码头”的依赖，其中包括“的javax.servlet-API” 3.1.0依赖。我们排除“弹簧引导启动-tomcat的”依赖性和“弹簧引导起动网”的依赖，只要是安全的。

但我们调查发现，在我们的项目的依赖，我们在某种程度上也有这个servlet-API 2.5依赖（这依赖从其他依赖继承）。

在3.1.0中，javax.servlet.ServletContext具有方法“addServlet”。

在2.5，它不具有此方法。

然后，我们了解到，行家随机在我们的应用程序使用的版本3.1.0或2.5版本。当它随机使用3.1.0，应用程序正常启动。当随机地使用2.5，不具有所述方法“addServlet”，它投掷“的NoSuchMethodError”异常。

为了解决这个问题，在pom.xml我们只是排除了隐藏的2.5“的javax.servlet”依赖性：
