springmvc添加mock json的支持

在springmvc中 添加对服务器classPath下的json文件解析之后返回的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;
}
}

  

相应的也可以增加其他的类型支持,比如string数据, 或者是其他的。由于 springmvc rest接口默认会使用json的转化器,所以需要转化成对应的json格式
