SpringMVC參數(shù)傳遞的方式有幾種？小編來(lái)告訴大家。

1.簡(jiǎn)單的ajax參數(shù)請(qǐng)求

public class TestParamController extends BaseController {
    @RequestMapping(value = "index", method = RequestMethod.GET)
    public String index(Model model) {
        return "testParam";
    }
    @RequestMapping(value = "test")
    @ResponseBody

6.Java代碼同時(shí)上傳代碼和附件

import org.apache.http.HttpEntity;
import org.apache.http.ParseException;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import java.io.File;
import java.io.IOException;
public final class Test {
    public static void main(String[] args) throws IOException {
        HttpPost httpPost = new HttpPost("http://xxxx:8080/yyyy//deviceConfig/uploadLogs.json");
        CloseableHttpClient client = HttpClientBuilder.create().build();
        CloseableHttpResponse resp = null;
        String respondBody = null;
        try {
            RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(200000).setSocketTimeout(200000000).build();
            httpPost.setConfig(requestConfig);
            MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
            multipartEntityBuilder.addBinaryBody("file", new File("/var/root/Desktop/aaa.txt"));//附件
            multipartEntityBuilder.addTextBody("logOperationId", "18");//普通參數(shù)
            HttpEntity httpEntity = multipartEntityBuilder.build();
            httpPost.setEntity(httpEntity);
            resp = client.execute(httpPost);
            respondBody = EntityUtils.toString(resp.getEntity());
            System.out.println(respondBody);
        } catch (IOException | ParseException e) {
            e.printStackTrace();
        } finally {
            resp.close();
        }
    }
}
@ResponseBody
    @RequestMapping(value = "uploadLogs")
    public Map<String, Object> uploadLogs(@RequestParam("file") CommonsMultipartFile file, Integer logOperationId) throws Exception {
        Map<String, Object> result = new HashMap<>();
        //TODO 操作參數(shù)
        return result;
    }

Java代碼上傳file和text

public static void main(String[] args) throws IOException {
        HttpPost httpPost = new HttpPost("http://localhost:8080/long_river/xxx/yyy.json");
        CloseableHttpClient client = HttpClientBuilder.create().build();
        CloseableHttpResponse resp = null;
        String respondBody = null;
        try {
            RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(200000).setSocketTimeout(200000000).build();
            httpPost.setConfig(requestConfig);
            MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
            multipartEntityBuilder.addBinaryBody("files", new File("/var/root/Desktop/testMap.html"));
            multipartEntityBuilder.addBinaryBody("files", new File("/var/root/Desktop/menu.html"));
            multipartEntityBuilder.addTextBody("deviceIds", "18");
            multipartEntityBuilder.addTextBody("deviceIds", "19");
            HttpEntity httpEntity = multipartEntityBuilder.build();
            httpPost.setEntity(httpEntity);
            resp = client.execute(httpPost);
            respondBody = EntityUtils.toString(resp.getEntity());
            System.out.println(respondBody);
        } catch (IOException | ParseException e) {
            e.printStackTrace();
        } finally {
            resp.close();
        }
    }
