springmvc添加mock json的支援，springmvcjson

在springmvc中 添加對伺服器classPath下的json檔案解析之後返回的mock功能：

 

import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import java.net.URL;import java.net.URLConnection;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import com.fasterxml.jackson.databind.JsonNode;import com.fasterxml.jackson.databind.ObjectMapper;@RestController@RequestMapping("/mock")public class MockController {    @RequestMapping(value = "/{module}/{action}", method = RequestMethod.POST)    public JsonNode mockContent(@PathVariable String module, @PathVariable String action, HttpServletRequest request,            HttpServletResponse response) {        JsonNode actualObj = null;        InputStream fis = null;        try {            ClassLoader ctxLoader = Thread.currentThread().getContextClassLoader();            URL resURL = ctxLoader.getResource(action + ".json");            URLConnection resConn = resURL.openConnection();            resConn.setUseCaches(false);            fis = resConn.getInputStream();            StringBuilder builder = new StringBuilder();            int ch;            while ((ch = fis.read()) != -1) {                builder.append((char) ch);            }            ObjectMapper mapper = new ObjectMapper();            actualObj = mapper.readTree(builder.toString());        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } finally {            if (fis != null) {                try {                    fis.close();                } catch (IOException e) {                }            }        }        return actualObj;    }}

　　

相應的也可以增加其他的類型支援，比如string資料， 或者是其他的。由於 springmvc rest介面預設會使用json的轉化器，所以需要轉化成對應的json格式
