基于dubbo从传统MVC架构转向SOA架构分布式设计2--（mvc->soa）

下面运用到一个MVC架构的小项目例子，这个例子我也是随便找的，也就之前学习mybaits的时候用的，springmvc+mybaits的

开始改造！

1.创建一个maven的parent项目：

把不要的文件都删除留下下面这样就可以了：

pom.xml文件修改为：

<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">  <modelVersion>4.0.0</modelVersion>  <groupId>com.cwh.soa</groupId>  <artifactId>ms-soa-parent</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>pom</packaging>  <build/>  <modules>  <module>ms-soa-user</module>  </modules>  <properties><junit.version>4.10</junit.version><spring-test.version>3.2.8.RELEASE</spring-test.version><mysql.version>5.1.22</mysql.version><spring-core.version>3.2.8.RELEASE</spring-core.version><spring-context.version>3.2.8.RELEASE</spring-context.version><spring-tx.version>3.2.8.RELEASE</spring-tx.version><spring-jdbc.version>3.2.8.RELEASE</spring-jdbc.version><spring-webmvc.version>3.2.8.RELEASE</spring-webmvc.version><mybatis.version>3.2.7</mybatis.version><mybatis-spring.version>1.2.2</mybatis-spring.version><aspectjweaver.version>1.8.1</aspectjweaver.version><jackson-core-asl.version>1.9.2</jackson-core-asl.version><jackson-mapper-asl.version>1.9.2</jackson-mapper-asl.version><javax.servlet-api.version>3.1.0</javax.servlet-api.version><log4j.version>1.2.16</log4j.version><commons-dbcp.version>1.2.1</commons-dbcp.version><fastjson.version>1.1.37</fastjson.version><jstl.version>1.1.0</jstl.version><standard.version>1.1.0</standard.version><commons-configuration.version>1.6</commons-configuration.version><commons-fileupload.version>1.2.1</commons-fileupload.version><dubbo.version>2.5.7</dubbo.version></properties><dependencyManagement><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring-test.version}</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring-core.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring-context.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring-tx.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring-jdbc.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring-webmvc.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis-spring.version}</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>${aspectjweaver.version}</version></dependency><dependency><groupId>org.codehaus.jackson</groupId><artifactId>jackson-core-asl</artifactId><version>${jackson-core-asl.version}</version></dependency><dependency><groupId>org.codehaus.jackson</groupId><artifactId>jackson-mapper-asl</artifactId><version>${jackson-mapper-asl.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>${javax.servlet-api.version}</version><scope>provided</scope></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4j.version}</version></dependency><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>${commons-fileupload.version}</version></dependency><dependency><groupId>commons-dbcp</groupId>    <artifactId>commons-dbcp</artifactId><version>${commons-dbcp.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>${fastjson.version}</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>${jstl.version}</version></dependency><dependency><groupId>taglibs</groupId><artifactId>standard</artifactId><version>${standard.version}</version></dependency><dependency>            <groupId>com.alibaba</groupId>            <artifactId>dubbo</artifactId>            <version>${dubbo.version}</version>        </dependency><dependency><groupId>commons-configuration</groupId><artifactId>commons-configuration</artifactId><version>${commons-configuration.version}</version></dependency></dependencies></dependencyManagement></project>

2.在ms-sao-parent右击 

new一个maven module project,我们就做一个user简单的提供服务模块吧

3.先从接口入手在ms-soa-user右击新建一个module，名为：ms-soa-user-api参考上面，不再赘述

从旧项目中拷贝需要的的文件，目录结构如下：

User.java:

package com.cwh.model;public class User {       private int id;    private String userName;    private String userAge;    private String userAddress;       public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getUserAge() {        return userAge;    }    public void setUserAge(String userAge) {        this.userAge = userAge;    }    public String getUserAddress() {        return userAddress;    }    public void setUserAddress(String userAddress) {        this.userAddress = userAddress;    }}

UserService.java:

package com.cwh.service;import java.util.List;import com.cwh.model.User;public interface UserService {public List<User>getUser(String userName);}

pom.xml:

<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">  <modelVersion>4.0.0</modelVersion>  <parent>    <groupId>com.cwh.soa</groupId>    <artifactId>ms-soa-user</artifactId>    <version>0.0.1-SNAPSHOT</version>  </parent>  <groupId>com.cwh.soa</groupId>  <artifactId>ms-soa-user-api</artifactId>  <version>0.0.1-SNAPSHOT</version>  <name>ms-soa-user-api</name>    <build>  <plugins>  <plugin>  <artifactId>maven-war-plugin</artifactId>  <configuration>  <version>3.0</version>  </configuration>  </plugin>  </plugins>  </build></project>

4.ok这样就完成一个接口模块

5.实现user服务提供者模块:

5.1在ms-soa-user右击新建一个module，名为：ms-soa-user-core参考上面，不再赘述

5.2拷贝所需文件，项目结构如上

pom.xml文件：

<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">  <modelVersion>4.0.0</modelVersion>  <parent>    <groupId>com.cwh.soa</groupId>    <artifactId>ms-soa-user</artifactId>    <version>0.0.1-SNAPSHOT</version>  </parent>  <artifactId>ms-soa-user-core</artifactId>  <packaging>war</packaging>  <dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId></dependency><dependency><groupId>commons-dbcp</groupId><artifactId>commons-dbcp</artifactId></dependency><dependency><groupId>commons-configuration</groupId><artifactId>commons-configuration</artifactId></dependency><dependency>            <groupId>com.alibaba</groupId>            <artifactId>dubbo</artifactId>        </dependency><dependency><groupId>com.cwh.soa</groupId><artifactId>ms-soa-user-api</artifactId><version>0.0.1-SNAPSHOT</version></dependency></dependencies>  <build>  <plugins>  <plugin>  <artifactId>maven-war-plugin</artifactId>  <configuration>  <version>3.0</version>  </configuration>  </plugin>  </plugins>  </build></project>

user.java:

package com.cwh.model;import java.io.Serializable;public class User implements Serializable{       private int id;    private String userName;    private String userAge;    private String userAddress;       public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getUserAge() {        return userAge;    }    public void setUserAge(String userAge) {        this.userAge = userAge;    }    public String getUserAddress() {        return userAddress;    }    public void setUserAddress(String userAddress) {        this.userAddress = userAddress;    }}

说明：注意下这里user必须序列化

user.xml

5.3ok这样就可以啦；启动Provider;

6.编写web消费者项目
6.1在ms-soa-user右击新建一个module，名为：ms-soa-user-web参考上面，不再赘述
右击该项目，修改为web项目：

6.2右击项目修改配置：

6.3ok部署到tomcat

浏览器访问即可

注意：纠正一点，在ms-soa-user-api中以及提供了User这个类了，后面ms-soa-user-core和ms-soa-user-web中就不需要在加这些model了，直接序列化api中的User即可
