dubbo使用記錄

一.引入相關包

<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.6</version>
</dependency>

<dependency>
<groupId>com.github.sgroschupf</groupId>
<artifactId>zkclient</artifactId>
<version>0.1</version>
</dependency>

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.4.9</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>

<dependency>
<groupId>com.caucho</groupId>
<artifactId>hessian</artifactId>
<version>4.0.7</version>
</dependency>

因爲需要 zookeeper 做集羣管理，需要 zookeeper的客戶端包 zkclient 因爲這裏面的圖片上傳服務是用的 hessian協議通信的，需要用到 hessian包

二 .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:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- 提供方應用信息，用於計算依賴關係 -->
<dubbo:application name="pz998-app" />

<!-- 使用zookeeper廣播註冊中心暴露服務地址 -->
<dubbo:registry protocol="zookeeper" address="${dubbo.address}" />

<dubbo:reference id="uploadService"
interface="com.jztey.filecenter.service.UploadService" />

</beans>

注意 com.jztey.filecenter.service.UploadService 配置的接口包路徑要與服務端一致

三.調用

@RequestMapping(value = "/uploadFile")
@ResponseBody
public Object uploadFile(HttpServletRequest request) throws IOException {
System.out.println("開始上傳......");
ResponseVoRpc resp = new ResponseVoRpc();

try{
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
StringBuffer stringBuf = new StringBuffer();
for (Iterator it = multipartRequest.getFileNames(); it.hasNext();) {
String key = (String) it.next();
MultipartFile imgFile = multipartRequest.getFile(key);
byte[] data = imgFile.getBytes();
String path = uploadService.upload(data, "", new HashMap<String, String>());
System.out.println("返回地址："+path);
stringBuf.append(commonSelectService.getApiJkdaRoot()+"/"+path);
}

Map<String, Object> result = new HashMap<String, Object>();
result.put("fileAbsolutePath",stringBuf.toString());
resp.setCode(ResponseVoRpc.CODE_COMMON_SUCCESS);
resp.setDatas(result);
}catch(Exception e){
e.printStackTrace();
resp.setCode(ResponseVoRpc.CODE_COMMON_FAILED);
resp.setCodeMsg("上傳異常");
}
return resp;
}
