• 项目管理工具maven(二)


    整合ssh框架

    2.1 依赖传递

    只添加了一个struts2-core依赖,发现项目中出现了很多jar

    这种情况 依赖传递

     

    2.2 依赖版本冲突的解决

    1、 第一声明优先原则

     
    <dependencies>
      <!--   spring-beans-4.2.4 -->
       <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-context</artifactId>
       <version>4.2.4.RELEASE</version>
       </dependency>
    
    <!--   spring-beans-3.0.5 -->
    
       <dependency>
    
       <groupId>org.apache.struts</groupId>
    
       <artifactId>struts2-spring-plugin</artifactId>
    
       <version>2.3.24</version>
    
       </dependency>

    2、 路径近者优先原则

    自己添加jar

    <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-beans</artifactId>
       <version>4.2.4.RELEASE</version>
       </dependency>

    3、 排除原则

       <dependency>
       <groupId>org.apache.struts</groupId>
       <artifactId>struts2-spring-plugin</artifactId>
       <version>2.3.24</version>
       <exclusions>
         <exclusion>
           <groupId>org.springframework</groupId>
           <artifactId>spring-beans</artifactId>
         </exclusion>
       </exclusions>
       </dependency>

    4、 版本锁定原则

    <properties>
    <spring.version>4.2.4.RELEASE</spring.version>
    <hibernate.version>5.0.7.Final</hibernate.version>
    <struts.version>2.3.24</struts.version>
    </properties>
    <!-- 锁定版本,struts2-2.3.24、spring4.2.4、hibernate5.0.7 -->
    <dependencyManagement>
    <dependencies>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
    </dependency>
    </dependencies>
    </dependencyManagement>

    需求:

    传客户ID 页面上显示客户信息

    准备数据库

    2.3 构建项目

    1、 创建数据库,

     

    2、 执行准备好的sql脚本

    3、 完善pom.xml文件,把ssh相关的依赖都添加上去

      <!-- 属性 -->
    <properties>
    <spring.version>4.2.4.RELEASE</spring.version>
    <hibernate.version>5.0.7.Final</hibernate.version>

    <!-- 可以灵活配置端口号 -->
    <port>8080</port>
    </configuration>
    </plugin>
    </plugins>
    </build>

    4、 完成实体类代码

     

    5、 完成dao代码

    接口

    package cn.itcast.dao;
    import cn.itcast.entity.Customer;
    
    public interface CustomerDao {
    public Customer getById(Long id);
    }

    实现类

    package com.itcast.dao.impl;
    import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
    import cn.itcast.dao.CustomerDao;
    import cn.itcast.entity.Customer;
    
    public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {
    
    @Override
    public Customer getById(Long id) {
    return this.getHibernateTemplate().get(Customer.class, id);
    }
    
    }

    6、 完成service代码

    接口

    package com.itcast.service;
    import cn.itcast.entity.Customer;
    public interface CustomerService { public Customer getById(Long id); }

    实现类

    package com.itcast.service.impl;
    
    import com.itcast.service.CustomerService;
    
    import cn.itcast.dao.CustomerDao;
    import cn.itcast.entity.Customer;
    
    public class CustomerServiceImpl implements CustomerService {
    private CustomerDao  customerDao;
    public void setCustomerDao(CustomerDao customerDao) {
      this.customerDao = customerDao;
    }
    @Override
    public Customer getById(Long id) {
      return customerDao.getById(id);
    }
    }

    7、 完成action代码

    package cn.itcast.action;
    import com.itcast.service.CustomerService;
    import com.opensymphony.xwork2.ActionSupport;
    import cn.itcast.entity.Customer;
    
    public class CutomerAction extends ActionSupport {
    
    //两个成员变量
    private Customer  customer;
    private Long custId;
    public Customer getCustomer() {
    return customer;
    }
    public void setCustomer(Customer customer) {
    
      this.customer = customer;
    
    }
    private CustomerService customerService;
      public void setCustomerService(CustomerService customerService) {
        this.customerService = customerService;
    }
    public Long getCustId() {
    return custId;
    }
    public void setCustId(Long custId) {
    this.custId = custId;
    }
    public String findById(){
    customer = customerService.getById(custId);
    return SUCCESS;
    }
    }

    8、 拷贝配置文件并修改

    从如下图位置拿到配置文件

     

    放入到 src/main/resources目录中

    修改内容

    9、 修改web.xml 添加spring的监听

    <listener>
    
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    
    </listener>
    
    <context-param>
    
    <param-name>contextConfigLocation</param-name>
    
    <param-value>classpath:applicationContext.xml</param-value>
    
    </context-param>

    10、 运行项目

    分模块开发

    依赖范围对依赖传递造成的影响(了解)

     

    父工程来管理   聚合

    3.1 创建父工程:

    1

     

    2、创建出的父工程如下

     

    3、在pom.Xml中添加以下信息:

      <!-- 属性 -->
    <properties>
    <spring.version>4.2.4.RELEASE</spring.version>
    <hibernate.version>5.0.7.Final</hibernate.version>

    <!-- 可以灵活配置端口号 -->
    <port>8080</port>
    </configuration>
    </plugin>
    </plugins>
    </build>

    4、发布到本地仓库

      dao  service  web

    3.2 创建dao子模块

    1、在ssh-parent项目上右击 ,创建时选择 Maven Module

     

    2、填写子模块名称ssh-dao

     

    3、把属于dao的代码拷贝到 该模块中:

     

    4、完成后发布到本地仓库中

    3.3 创建service子模块

    1、创建方式如上:

    2、把属于service的代码拷贝到该工程中

     

    3、发布到本地仓库中

    3.4 创建Action子模块

    1、选择war的打包方式

     

    5、 拷贝属于action的代码和配置文件

     

    6、 修改web.xml  添加spring监听

    <listener>
    
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    
    </listener>
    
     
    
    <context-param>
    
     <param-name>contextConfigLocation</param-name>
    
     <param-value>classpath*:applicationContext-*.xml</param-value>
    
    </context-param>

    4、添加页面:

     

    私服 nexus

    安装nexus

     

    启动服务

     

    启动失败的解决方法:

     

    登录nexus

    用户名/密码  admin/admin123

    仓库类型

     

    Virtual   虚拟仓库

    Proxy  代理仓库

    Hosted  宿主仓库  本地仓库

    Group

    需求:

    dao放到私服上,然后service从私服上下载

    需求 :将ssh_dao的这个工程打成jar包,并放入到私服上去.

    4.1 上传dao

    第一步: 需要在客户端即部署dao工程的电脑上配置 maven环境,并修改 settings.xml 文件,配置连接私服的用户和密码 。

    此用户名和密码用于私服校验,因为私服需要知道上传都 的账号和密码 是否和私服中的账号和密码 一致。

        <server>
          <id>releases</id>
          <username>admin</username>
          <password>admin123</password>
        </server>
    <server>
          <id>snapshots</id>
          <username>admin</username>
          <password>admin123</password>
        </server>

    第二步: 配置项目pom.xml

    配置私服仓库的地址,本公司的自己的jar包会上传到私服的宿主仓库,根据工程的版本号决定上传到哪个宿主仓库,如果版本为release则上传到私服的release仓库,如果版本为snapshot则上传到私服的snapshot仓库

      <distributionManagement>
    
       <repository>
    
       <id>releases</id>
    
    <url>http://localhost:8081/nexus/content/repositories/releases/</url>
    
       </repository> 
    
       <snapshotRepository>
    
       <id>snapshots</id>
    
    <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
    
       </snapshotRepository> 
    
      </distributionManagement>

    注意:pom.xml这里<id> settings.xml 配置 <id> 对应!

    第三步:执行deploy命令发布到私服

    4.2 下载dao

    第一步 修改settings.xml

    <profile>   
    <!--profile的id-->
        <id>dev</id>   
        <repositories>   
          <repository>  
    <!--仓库id,repositories可以配置多个仓库,保证id不重复-->
            <id>nexus</id>   
    <!--仓库地址,即nexus仓库组的地址-->
            <url>http://localhost:8081/nexus/content/groups/public/</url>   
    <!--是否下载releases构件-->
            <releases>   
              <enabled>true</enabled>   
            </releases>   
    <!--是否下载snapshots构件-->
            <snapshots>   
              <enabled>true</enabled>   
            </snapshots>   
          </repository>   
        </repositories>  
     <pluginRepositories>  
         <!-- 插件仓库,maven的运行依赖插件,也需要从私服下载插件 -->
            <pluginRepository>  
             <!-- 插件仓库的id不允许重复,如果重复后边配置会覆盖前边 -->
                <id>public</id>  
                <name>Public Repositories</name>  
                <url>http://localhost:8081/nexus/content/groups/public/</url>  
            </pluginRepository>  
        </pluginRepositories>  
      </profile>  
    
      <activeProfiles>
        <activeProfile>dev</activeProfile>
      </activeProfiles>

    第二步 删除本地仓库中的dao

    第三步 update service工程,出现以下信息说明已经成功
