当 spring-boot 运行时，IntelliJ 进程以退出代码 0 完成

Question

从 IntelliJ-Idea 启动 spring-boot 应用程序时出现问题。 通过终端运行应用程序时我没有这个问题。

:: Spring Boot ::        (v1.2.1.RELEASE)

2015-09-24 12:22:44.274  WARN 22380 --- [           main] n.sf.ehcache.config.CacheConfiguration   : Cache 'publicationsCount' is set to eternal but also has TTI/TTL set.  To avoid this warning, clean up the config removing conflicting values of eternal, TTI and TTL. Effective configuration for Cache 'publicationsCount' will be eternal='true', timeToIdleSeconds='0', timeToLiveSeconds='0'.

Process finished with exit code 0

我认为这个警告并没有引起它。 可能是什么原因？

Answer 1

删除spring-boot-starter-tomcat依赖项的提供范围对我有帮助。

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

Answer 2

我从https://start.spring.io/ (sprint initializr) 创建了一个简单的项目，并添加了一个简单的控制器来运行应用程序。

@RestController
public class testController {

    @GetMapping(value="/")
    //@RequestMapping(value="/",method=RequestMethod.GET)
    public String hello(){
        return "Hello World!!";
    }
}

但它没有开始，因为我的 pom 没有

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

添加此后，我的应用程序开始...

2019-11-05 14:33:32.302  INFO 39079 --- [           main] o.s.s.web.DefaultSecurityFilterChain     : Creating filter chain: any request, [org.springframework.security.web.context.request.async.WebAsyncManagerIntegrationFilter@dd20ebc, org.springframework.security.web.context.SecurityContextPersistenceFilter@57b1ec84, org.springframework.security.web.header.HeaderWriterFilter@2c2a7d53, org.springframework.security.web.csrf.CsrfFilter@b9b97ad, org.springframework.security.web.authentication.logout.LogoutFilter@29f3185c, org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter@4ffa7041, org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter@2c2a903f, org.springframework.security.web.authentication.ui.DefaultLogoutPageGeneratingFilter@6c70b7c3, org.springframework.security.web.authentication.www.BasicAuthenticationFilter@48d44b46, org.springframework.security.web.savedrequest.RequestCacheAwareFilter@5cbe95b1, org.springframework.security.web.servletapi.SecurityContextHolderAwareRequestFilter@11ad095c, org.springframework.security.web.authentication.AnonymousAuthenticationFilter@16a09809, org.springframework.security.web.session.SessionManagementFilter@1de85972, org.springframework.security.web.access.ExceptionTranslationFilter@4a122e68, org.springframework.security.web.access.intercept.FilterSecurityInterceptor@5d37aa0f]

这是我的 pom 依赖项：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

            <artifactId>spring-security-test</artifactId>
            <scope>test</scope>
        </dependency>
</dependencies>

注意：您可能不需要上述所有依赖项。

Answer 3

在 pom.xml 中添加以下依赖项：

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <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>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <scope>test</scope>
        </dependency>

Answer 4

添加 spring boot starter web 解决了我的问题

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

Answer 5

在我的情况下，我开始 intelliJ 作为

管理员

，然后它的工作原理确保你有 tomcat 依赖

 <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-core</artifactId>
        <version>9.0.29</version>
    </dependency>

Answer 6

在 pom.xml 中使用以下依赖项，以及加载 maven 更改（ctrl+shift+o）解决了我的问题。

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

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

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

Answer 7

就我而言，以下之间略有不同：

• 只需在 IntelliJ 中最明显的底部单击运行，然后...
• 在 src/main/java/com.exampler.yourapplication 中查找默认控制器，右键单击并按 Run 在那里。

第二个选项只是正确运行项目。

Answer 8

如果您从https://start.spring.io/ (sprint initializr) 创建项目gradle模板，则需要在 build.gradle 文件中添加org.springframework.boot:spring-boot-starter-web依赖项。

// you need to add this dependency to run spring boot correctly
implementation 'org.springframework.boot:spring-boot-starter-web'   

Answer 9

如果以下属性已添加到 allication.properties 文件中，则需要将其删除。 此属性用于删除 Web 容器。

spring.main.web-application-type=none

就我而言，我忘记删除它，一旦删除，问题就解决了

Answer 10

如果我们创建项目的方式错误或 pom.xml 依赖项错误，则会出现此问题。 对我来说，从 spring 初始化程序重新创建项目是可行的。
