關於Spring--hessian遠端呼叫介面服務配置
阿新 • • 發佈:2018-12-18
maven依賴hessian的jar包如下:
<dependency>
<groupId>com.caucho</groupId>
<artifactId>hessian</artifactId>
<version>4.0.37</version>
</dependency>
服務端:
1、建立hession-servlet.xml檔案
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <context:annotation-config /> <!-- 定義普通的bean例項,介面的實現類 --> <bean id="personImpl" class="com.test.service.impl.PersonServiceImpl"/> <!-- 使用HessianServiceExporter 將普通bean匯出成Hessian服務,將介面暴露給外部給客戶端呼叫,/personService.remote為遠端呼叫介面的url --> <bean name="/personService.remote" class="org.springframework.remoting.caucho.HessianServiceExporter"> <!-- 需要匯出的目標bean(匯出介面的實現類) --> <property name="service" ref="personImpl"/> <!-- Hessian服務的介面 --> <property name="serviceInterface" value="com.test.service.PersonService"/> </bean> </beans>
2、配置web.xml檔案
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_test" version="3.0"> <display-name>test</display-name> <context-param> <param-name>webAppRootKey</param-name> <param-value>test.root</param-value> </context-param> <!-- springMVC配置 --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/springMVC-servlet.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- hessian遠端呼叫配置,設定mvc攔截器,用來攔截遠端呼叫的介面的url --> <servlet> <servlet-name>hessian</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--上面配置的xml檔案--> <param-value>classpath:config/hessian-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>hessian</servlet-name> <!--攔截的路徑--> <url-pattern>/hessian/*</url-pattern> </servlet-mapping> </web-app>
3、將暴露的介面(介面需要用到的實體類model)匯出為jar包,供客戶端直接引用
客戶端:
1、引用服務端提供的jar包
2、applicationContext.xml檔案的配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 啟用註解 --> <context:annotation-config /> <!-- 建立bean代理物件,呼叫遠端介面服務,id:要與@Autowired注入的名稱相同 --> <bean id="personService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean"> <property name="overloadEnabled" value="true" /> <!-- 呼叫的遠端介面url --> <property name="serviceUrl"> <value>http://127.0.0.1:8080/test/hessian/personService.remote</value> </property> <!-- 遠端呼叫服務介面(本地的介面),該介面要與服務端的介面完全一致 --> <property name="serviceInterface"> <value>com.test.service.PersonService</value> </property> </bean> </beans>
3、客戶端在Cotroller層可直接@autowired注入介面服務(hessian代理物件)
package com.myproject.controller;
import java.util.List;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.test.entity.Person;
import com.test.service.PersonService;
@Controller
@RequestMapping("/test")
public class TestController {
private static final Logger log = LoggerFactory.getLogger(TestController.class);
/**
* hession介面代理物件
*/
@Autowired
private PersonService personService;
@RequestMapping("/test")
@ResponseBody
public List<Person> personList(){
List<Person> list = personService.list();
System.out.println("遠端呼叫介面輸出");
return list;
}
}
