maven項目打成jar包的類沒法注入

maven項目打jar包後類沒法注入，須要生成目錄，添加maven插件

<plugin>  
     <groupId>org.apache.maven.plugins</groupId>  
     <artifactId>maven-jar-plugin</artifactId>  
     <version>3.1.2</version>  
     <configuration>
        <archive> 
            <manifest> 
                <addDefaultImplementationEntries>true</addDefaultImplementationEntries>  
            </manifest> 
        </archive> 
     </configuration>
 </plugin>
