具有Maven模块依赖项的Spring Boot无法正常工作

标签： java spring-boot module pom.xml

在一个具有Maven模块依赖项的Spring Boot中运行一个简单的应用程序非常有用。我之所以尝试运行，是因为我必须将J2EE应用程序迁移到具有7个模块的Springboot中，但是我无法使用一个简单的模块来运行。

这是我尝试的方式。

我下载了一个示例应用程序，并使用pom包装使其成为父项。

            </plugin>
        </plugins>
    </build>

</project>

并如下创建了一个Maven依赖模块

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>pes</artifactId>
        <groupId>com.it.pes</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <packaging>war</packaging>
    <artifactId>PesPdfExtractService</artifactId>

</project>

默认情况下，Spring Boot应用程序类位于父模块上，因此我将其放置在子模块中

package com.it.pes.pdfextract.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

    @SpringBootApplication
    @ComponentScan(basePackages = "com.it.pes.pdfextract.controller")
    public class PesApplication {

        public static void main(String[] args) {

            SpringApplication.run(PesApplication.class, args);
        }
    }

最后创建了一个控制器来测试应用程序是否正常运行。

package com.it.pes.pdfextract.controller;


import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/")
public class TestController {
    @RequestMapping("/test")
    public String test(){

        return "hello spring boot world";
    }
}

当我执行mvn clean install时，它成功构建，但是tom cat根本无法启动，并呈现以下消息
