maven 项目打可执行jar包

时间:2021-12-18 05:40:41
昨晚,突然就来了紧急任务。
验签较慢,着手优化,发来一个demo。
 
 
首先需要把该demo部署在Linux上。
 
 
该项目是maven 项目,所以用maven打个jar包,打完jar包之后,可在Linux上直接执行 java -jar XXXX.jar
 
所以在pom.xml文件中添加
          <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <appendAssemblyId>false</appendAssemblyId>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <!-- 此处指定main方法入口的class -->
                            <mainClass>test.SignTestMain</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>assembly</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
这段代码就好了。
 
注意:这是添加在<build>和<plugins>里面的,完整的如下。
     <build>
            <plugins>
                  <plugin>
                        <artifactId>maven-compiler-plugin</artifactId>
                        <configuration>
                              <source>1.6</source>
                              <target>1.6</target>
                              <encoding>UTF-8</encoding>
                        </configuration>
                  </plugin>
                  <!-- <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-jar-plugin</artifactId>
                        <configuration>
                              <source>1.8</source>
                              <target>1.8</target>
                              <archive>
                                    <manifest>
                                                     <mainClass>test.SignTestMain</mainClass>
                                    </manifest>
                              </archive>
                              <classesDirectory>
                              </classesDirectory>
                        </configuration>
                  </plugin> -->
                   <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <appendAssemblyId>false</appendAssemblyId>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <!-- 此处指定main方法入口的class -->
                            <mainClass>test.SignTestMain</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>assembly</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            </plugins>
      </build>
被注释掉的也是打jar包的一种方式,但是你采用这种方式你maven项目所依赖的jar不会被打进去,所以不合适。
