一、今天完成的事

Tuscany整合到之前的项目中

导入Tuscany包

<!--tuscanyRmi包-->

<dependency>

<groupId>org.apache.tuscany.sca</groupId>

<artifactId>tuscany-sca-api</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca</groupId>

<artifactId>tuscany-base-runtime</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca.aggregation</groupId>

<artifactId>tuscany-binding-rmi-runtime-aggregation</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca.aggregation</groupId>

<artifactId>tuscany-binding-ws-runtime-axis2-aggregation</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca</groupId>

<artifactId>tuscany-implementation-spring-runtime</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca</groupId>

<artifactId>tuscany-assembly-xml</artifactId>

<version>2.0.1</version>

</dependency>

<dependency>

<groupId>org.apache.tuscany.sca</groupId>

<artifactId>tuscany-binding-rmi-runtime</artifactId>

<version>2.0.1</version>

<scope>runtime</scope>

</dependency>

server服务端

配置文件*.composite

<?xml version="1.0" encoding="UTF-8"?>

<composite

xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"

targetNamespace="http://com.jnshu.tuscanyService"

xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1"

name="serviceOne">

<component name="serviceOne">

<implementation.spring location="applicationContext.xml"/>

<service name="StudentService">

<interface.java interface="com.ksy.service.StudentService"/>

<tuscany:binding.rmi uri="rmi://127.0.0.1:8881/studentService"/>

</service>

<service name="ProfessionService">

<interface.java interface="com.ksy.service.ProfessionService"/>

<tuscany:binding.rmi uri="rmi://127.0.0.1:8881/professionService"/>

</service>

<service name="UserService">

<interface.java interface="com.ksy.service.UserService"/>

<tuscany:binding.rmi uri="rmi://127.0.0.1:8881/userService"/>

</service>

</component>

applicationContext

<!-- type里是service接口路径，target里是实现类在ioc容器中的id，就是上面bean的id -->

<sca:service name="StudentService" type="com.ksy.service.StudentService" target="StudentServiceImpl"/>

<bean id="StudentServiceImpl" class="com.ksy.service.serviceImpl.StudentServiceImpl"/>

<sca:service name="UserService" type="com.ksy.service.UserService" target="UserServiceImpl"/>

<bean id="UserServiceImpl" class="com.ksy.service.serviceImpl.UserServiceImpl"/>

<sca:service name="ProfessionService" type="com.ksy.service.ProfessionService" target="ProfessionServiceImpl"/>

<bean id="ProfessionServiceImpl" class="com.ksy.service.serviceImpl.ProfessionServiceImpl"/>

client客户端

使用try/catch方法随机访问server

StudentService studentService = null;

int code = new Random().nextInt(2);

if (code == 1) {

try {

studentService = (StudentService) Naming.lookup("rmi://127.0.0.1:8881/studentService");

} catch (Exception e) {

studentService = (StudentService) Naming.lookup("rmi://127.0.0.1:8882/studentService");

}

} else {

try {

studentService = (StudentService) Naming.lookup("rmi://127.0.0.1:8881/studentService");

} catch (Exception e) {

studentService = (StudentService) Naming.lookup("rmi://127.0.0.1:8882/studentService");

}

}

二、遇到的问题

遇到一些臭bug

注意一下几点

1.配置文件中一定要对应

<service name="StudentService">

<interface.java interface="com.ksy.service.StudentService"/>

<tuscany:binding.rmi uri="rmi://127.0.0.1:8881/studentService"/>

</service>

application

<sca:service name="UserService" type="com.ksy.service.UserService" target="UserServiceImpl"/>

<bean id="UserServiceImpl" class="com.ksy.service.serviceImpl.UserServiceImpl"/>

2.spring版本过高也会导致报错，尝试降版本

三、收获

四、明天的计划

部署到服务器中，任务总结
