1、直接将jar包放置到

src\main\webapp\WEB-INF\lib下 添加 
     
     
      org.apache.maven.plugins
     
    

    
     maven-compiler-plugin
        
    
     3.3
        
           
     1.7       
     
      1.7
            
     
      UTF-8
            
               
      
       src\main\webapp\WEB-INF\lib
             
         
      2、添加dependency

<artifactId>？</artifactId>

<version>1.0.0</version>

<scope>system</scope>

<systemPath>${project.basedir}/libs/？.jar</systemPath>

</dependency>

<plugin>

<configuration>

<webResources>

<resource>

<directory>libs</directory>
