spring boot打包war详细教程

2024-04-10 15:10:54

1.Application必须继承SpringBootServletInitializer

package com.java1234;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * 打包成war包时，必须继承SpringBootServletInitializer 
 * @author yqj234
 *
 */
@SpringBootApplication
public class JxcApplication extends SpringBootServletInitializer {

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

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

2.复写ServletInitializer类，继承SpringBootServletInitializer

package com.java1234;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(JxcApplication.class);
	}

}

3.PO.XML配置war包相关的参数

3.1 修改打包方式为war

3.2 去掉内嵌tomcate

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

3.3 添加javax.servlet

<dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>javax.servlet-api</artifactId>
           <version>3.1.0</version>
           <scope>provided</scope>
       </dependency>

3.4 添加tomcat

<dependency>
           <groupId>org.apache.tomcat</groupId>
           <artifactId>tomcat-servlet-api</artifactId>
           <version>9.0.41</version>
           <scope>provided</scope>
       </dependency>
