eclipse 打包springboot成jar

因为springboot到生产环境是在部署到jar或者war,推荐用jar比较方便

如下pom.xml

<?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"

                </plugin>
            </plugins>
        </pluginManagement>

    </build>
</project>

主要注意下：

<pluginManagement>
            <plugins>
                <plugin>
                    <artifactId>maven-resources-plugin</artifactId>
                    <configuration>
                        <encoding>utf-8</encoding>
                        <useDefaultDelimiters>true</useDefaultDelimiters>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
步骤：
1。选中项目，右击run as 顺序运行maven clean再maven install
2.打包成功之后，可以看到[INFO] BUILD SUCCESS ; 得到springbootWebSocket.jar包里有相关引用的jar
3.运行java -jar springbootWebSocket.jar

打包时注意：
1。不要在pom.xml引用关联外部的子模块或者父模块  2。因本项目使用websocket，在使用类SpringbootWebsocketApplicationTests测试时，

加上@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

package cn.huanzi.qch.springbootwebsocket;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class SpringbootWebsocketApplicationTests {

    @Test
    public void contextLoads() {
    }

}
