示例以下：

1.   新建Maven項目 exe-jar

 

2.   pom.xml

<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

    <dependencies>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.56</version>
        </dependency>

    </dependencies>

    <build>
        <finalName>${project.artifactId}</finalName>

        <plugins>

            <!-- 編譯插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>

                </configuration>
            </plugin>

            <!-- 打包插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                    </descriptorRefs>
                    <archive>
                        <manifest>

                            <!-- 主程序入口類 -->
                            <mainClass>com.java.demo.JsonDemo</mainClass>
                        </manifest>

                        </goals>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>
</project>

 

 

3.   JsonDemo.java

package com.java.demo;

import com.alibaba.fastjson.JSON;

public class JsonDemo {

    public static void main(String[] args) {
        System.out.println(JSON.toJSONString(args, true));
    }

}

 

4.   在項目上單擊右鍵 》 Run As 》 Maven build... 》。 以下圖：

 

 

在Goals 裏輸入 clean package ， 單擊【Run】。以下圖

 

 控制檯打出BUILD SUCCESS ，打包完成。

 

打開target 目錄，測試運行

在命令行窗口輸入

java -jar exe-jar.jar Hello Good Hi

回車執行，以下圖

 

 

 

控制檯打印結果：

["Hello","Good","Hi"]

 

 

 

打包成功。
