SpringMVC参数传递的方式有几种？小编来告诉大家。

1.简单的ajax参数请求

controller

import com.pandabus.framework.base.web.controller.BaseController;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping(value = "/testParam/")
public class TestParamController extends BaseController {
    @RequestMapping(value = "index", method = RequestMethod.GET)
    public String index(Model model) {
        return "testParam";
    }
    @RequestMapping(value = "test")
    @ResponseBody
    public Map<String, Object> test(String name, Integer age) throws Exception {
        Map<String, Object> result = new HashMap<>();
        result.put("name", name);
        result.put("age", age);
        return result;
    }
}

        url: 'test.json',
        type: 'post',
        data: {
            name: '二狗',
            age: 3
        },
        async: true,
        cache: false,
        success: function (data) {
            console.log(JSON.stringify(data));
        }
    });
</script>
</body>
</html>

2.ajax带数组参数请求

controller

import com.pandabus.framework.base.web.controller.BaseController;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping(value = "/testParam/")
public class TestParamController extends BaseController {
    @RequestMapping(value = "index", method = RequestMethod.GET)
    public String index(Model model) {
        return "testParam";
    }
    /**
     * @param name
     * @param food 页面的food:[1,2,3]会已 food[]:1,food[]:2,food[]:3形式发送过来，所以这里要给food参数起个food[]别名，这样才能接收到
     * @return
     * @throws Exception
     */
    @RequestMapping(value = "test")
    @ResponseBody
    public Map<String, Object> test(String name, @RequestParam(name = "food[]") String[] food) throws Exception {
        Map<String, Object> result = new HashMap<>();
        result.put("name", name);
        result.put("food", food);
        return result;
    }
}

jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</head>
<body>
<script type="text/javascript">

        url: 'test.json',
        type: 'post',
        data: {
            name: '二狗',
            food: ['狗粮','骨头','营养膏']
        },
        async: true,
        cache: false,
        success: function (data) {
            console.log(JSON.stringify(data));
        }
    });
</script>
</body>

3.ajax带对象请求

实体类

package com.pandabus.custom.controller;
public class Dog {
    private String name;
    private String[] food;
    private Integer age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String[] getFood() {
        return food;
    }
    public void setFood(String[] food) {
        this.food = food;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}

controller

import com.pandabus.framework.base.web.controller.BaseController;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping(value = "/testParam/")
public class TestParamController extends BaseController {
    @RequestMapping(value = "index", method = RequestMethod.GET)
    public String index(Model model) {
        return "testParam";
    }
    /***
     *
     * @param dog 需要添加@RequestBody注解，这样SpringMvc会把收到的JSON反序列化成实体
     * @return
     * @throws Exception
     */
    @RequestMapping(value = "test")
    @ResponseBody
    public Map<String, Object> test(@RequestBody Dog dog) throws Exception {
        Map<String, Object> result = new HashMap<>();
        result.put("dog", dog);
        return result;
    }
}

JSP

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    };
    $.ajax({
        url: 'test.json',
        type: 'post',
        contentType: 'application/json',//需要指定contentType
        data: JSON.stringify(dog),//传递对象的json
        async: true,
        cache: false,

6.Java代码同时上传代码和附件

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");//普通参数
            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 操作参数
        return result;
    }

Java代码上传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();
        }
    }
