Question

我正在尝试将在tomcat上运行的现有应用程序更改为SpringBoot。它一直运行到实际的SpringBoot启动。我有一个类似的应用程序在springBoot上运行。这就是我知道它一直运行到springboot。

我的主要方法：

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Main {

public static void main(String[] args) {
    //Every argument passed needs to become a system property
    for (String arg : args) {
        System.getProperties().setProperty(arg.split("=")[0], arg.split("=")[1]);
    }
    SpringApplication.run(Main.class, args);
}}

POM.xml有springboot父标记：

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.M4</version>
</parent>

我有springboot maven插件：

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>

属性具有开始标记：

<start-class>com.sample.requesthandler.Main</start-class>

依赖关系有starter-web和starter-acuator：

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

我尝试使用带有basePackages的@componentScan运行main方法，如下所示：

@ComponentScan(basePackages="com.sample.requesthandler")

这没有帮助。我尝试在主类的顶部添加@SpringBootApplication注释。这也没有用。

以下是完整日志：

我的其他项目在此行之后立即启动springBoot。

我错过了什么？提前谢谢。

Answer 1

尝试修改版本，例如

    <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath />
</parent>

Answer 2

问题出在logback.xml上。它有多个标签具有相同的格式。我已经更新了logback.xml并修复了问题。现在我可以正确启动spring boot应用程序了。

感谢您的每一个时间！

Answer 3

您的主类应该从Spring Boot实现CommandLineRunner接口。

从apache tomcat应用程序迁移后，Springboot应用程序无法启动
