springmvc使用@RequestBody报415问题解决

1、导入所需jar

jackson-annotations，jackson-databind，jackson-core。

2、开启mvc自动扫描注册映射器

<mvc:annotation-driven />
	<!--配置全局拦截器-->
	<mvc:interceptors>
		<bean class="com.zqf.marketing.aspect.ControllerInterceptor"></bean>
	</mvc:interceptors>
	<bean
			class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="mappingJackson2HttpMessageConverter" />
			</list>
		</property>
	</bean>
	<bean id="mappingJackson2HttpMessageConverter"
		  class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=UTF-8</value>
				<value>text/json;charset=UTF-8</value>
				<value>application/json;charset=UTF-8</value>
			</list>
		</property>
	</bean>

3、客户端请求类型要求

客户端的Content-Type 必须为application/json

4、示例整合

1、请求的封装

public static String postJsonBody(String url, Map<String, Object> paramsMap) {
        String result = null;
        CloseableHttpClient httpClient = getHttpClient();

        try {
            HttpPost httppost = new HttpPost(url);
            httppost.addHeader("charset", "UTF-8");
            httppost.addHeader("Content-Type", "application/json");

            String body = JsonUtils.writeValue(paramsMap);
            httppost.setEntity(new StringEntity(body, Charset.forName("UTF-8")));

            HttpResponse response = httpClient.execute(httppost);
            result = getPostResult(response);
            httpClient.close();
        } catch (Exception e) {
            log.error("post " + url + " exception", e);
        }

        return result;
    }

2、请求的发送

Map<String,Object> map = new HashMap<>();
        map.put("companyName","公司简称");
        map.put("pushTime","2018-11-29 16:39:23");
        map.put("signContent","sign");
        List<Map> list = new ArrayList<>();
        for(int k=1;k<10;k++){
            Map<String,Object> map2 = new HashMap<>();
            map2.put("telPhone","1841005570"+k);
            map2.put("scenario","营销剧本XX");
            list.add(map2);
        }
        map.put("content",list);
        System.out.println(JsonUtils.writeValue(map));
        String post = HttpUtils.postBody("url地址", JsonUtils.writeValue(map));
        System.out.println(post);
