maven使用

1,转换maven 项目为web 项目

2,maven项目在eclipse的library中没有Maven Dependencies

maven自动生成实体类：

<dependency>
   <groupId>com.codecreator</groupId>
   <artifactId>code-maven-plugin</artifactId>
   <version>1.7.2-SNAPSHOT</version>
</dependency>

<plugin>
   <groupId>com.codecreator</groupId>
   <artifactId>code-maven-plugin</artifactId>
   <version>1.7.2-SNAPSHOT</version>
   <configuration>
      <!-- 默认值 是 com.mysql.jdbc.Driver -->
      <driverClass>com.mysql.jdbc.Driver</driverClass>
      <dbUrl>jdbc:mysql://rm-wz900n8yw1hcct1r2o.mysql.rds.aliyuncs.com:3306/lock_db</dbUrl>
      <dbUser>lock_dba</dbUser>
      <dbPassword>lock_dba123</dbPassword>
      <bundleFiles>api.xml</bundleFiles>
      <packagePrefix>com.codecreator.</packagePrefix>
      <needDao>true</needDao>
      <tables>t_m_village</tables>
   </configuration>
</plugin>

mvn code:db2code

 

 

maven仓库配置：

settings.xml

<?xml version="1.0"?>  
<settings>  
<localRepository>/Users/zhiwei/.m2/repository</localRepository><!--需要改成自己的maven的本地仓库地址-->  
    <mirrors>  
        <mirror>  
            <id>alimaven</id>  
            <name>aliyun maven</name>  
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
            <mirrorOf>central</mirrorOf>  
        </mirror>  
    </mirrors>  
  <profiles>  
    <profile>  
       <id>nexus</id>   
        <repositories>  
            <repository>  
                <id>nexus</id>  
                <name>local private nexus</name>  
                <url>http://maven.oschina.net/content/groups/public/</url>

                    <enabled>true</enabled>  
                </releases>  
                <snapshots>  
                    <enabled>false</enabled>  
                </snapshots>  
            </repository>  
        </repositories>  
          
        <pluginRepositories>  
            <pluginRepository>  
            <id>nexus</id>  
            <name>local private nexus</name>  
            <url>http://maven.oschina.net/content/groups/public/</url>  
            <releases>

                <enabled>false</enabled>  
            </snapshots>  
            </pluginRepository>  
        </pluginRepositories>  
    </profile></profiles>  
</settings>

常用maven命令总结：
mvn -v //查看版本
mvn archetype:create //创建 Maven 项目
mvn compile //编译源代码
mvn test-compile //编译测试代码
mvn test //运行应用程序中的单元测试
mvn site //生成项目相关信息的网站
mvn package //依据项目生成 jar 文件
mvn install //在本地 Repository 中安装 jar
mvn -Dmaven.test.skip=true //忽略测试文档编译
mvn clean //清除目标目录中的生成结果
mvn clean compile //将.java类编译为.class文件
mvn clean package //进行打包
mvn clean test //执行单元测试
mvn clean deploy //部署到版本仓库
mvn clean install //使其他项目使用这个jar,会安装到maven本地仓库中
mvn archetype:generate //创建项目架构
mvn dependency:list //查看已解析依赖
mvn dependency:tree //看到依赖树
mvn dependency:analyze //查看依赖的工具
mvn help:system //从中央仓库下载文件至本地仓库
mvn help:active-profiles //查看当前激活的profiles
mvn help:all-profiles //查看所有profiles
mvn help:effective -pom //查看完整的pom信息
