1  在Myeclipse中准备两个maven demo. , 在 maven02中引入maven01

2 maven01 情况

Factory.java

1.  
   package learning;
2.  
    
3.  
   public class Factory {
4.  
   public static String createMessage(){
5.  
   String message = "hello maven1";
6.  
   return message;
7.  
   }
8.  
   }

pom.xml

1.  
   <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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

22.  
    <scope>provided</scope>
23.  
    </dependency>
24.  
    <dependency>
25.  
    <groupId>javax.servlet.jsp</groupId>
26.  
    <artifactId>jsp-api</artifactId>
27.  
    <version>2.1</version>
28.  
    <scope>provided</scope>
29.  
    </dependency>
30.  
    </dependencies>
31.  
    <build>
32.  
    <plugins>
33.  
    <plugin>
34.  
    <artifactId>maven-war-plugin</artifactId>
35.  
    </plugin>
36.  
    <plugin>
37.  
    <artifactId>maven-compiler-plugin</artifactId>
38.  
    <configuration>
39.  
    <source>1.5</source>
40.  
    <target>1.5</target>
41.  
    </configuration>
42.  
    </plugin>
43.  
    </plugins>
44.  
    </build>
45.  
    </project>

3  maven02 demo

maven02要引入maven01要引入,只要将maven01中pom.xml的groupId，artifactId,version放在maven02的pom.xml,

关键代码截图

Test.java做测试,直接调用Factory.createMessage

1.  
   package learning;
2.  
    
3.  
   public class Test {
4.  
    
5.  
    
6.  
   public static void main(String[] args) {
7.  
   String message = Factory.createMessage();
8.  
   System.out.println(message);
9.  
   }
10.  
     
11.  
    }

输出结果如下,说明maven2已经可以调用maven1中的代码.
