ajax Post JSON与SpringMVC

发布时间:2020-12-16 01:47:59 所属栏目:百科 来源:网络整理
导读:1. 配置文件 !-- 处理在类级别上的@RequestMapping注解 -- bean class = "org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" / !-- 处理方法级别上的@RequestMapping注解 -- bean class = "org.springframework.web.ser

1. 配置文件

<!-- 处理在类级别上的@RequestMapping注解 -->
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />

    <!-- 处理方法级别上的@RequestMapping注解 -->
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="stringConverter" />
                <ref bean="jsonConverter" />
            </list>
        </property>
    </bean>

    <bean id="stringConverter" class="org.springframework.http.converter.StringHttpMessageConverter">
        <property name="supportedMediaTypes" value="text/html;charset=UTF-8"/>
    </bean>

    <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes" value="application/json" />
    </bean>

2. 客户端javaScript代码

var orderData = {
    bookDate: "2015-11-23",siteType: UcConstant.Dojoy.Site.SITE_TYPE_WHOLE,siteStatus: UcConstant.Dojoy.Site.SITE_STATUS_OCCUPIED,sportType: sportType,siteBookingCarts: [{"siteID": 223,"siteName": "1号场地"}],totalPrice: 0
};
$.ajax({
    type: "POST",url: "site/siteOrderDetail",contentType: "application/json",data: JSON.stringify(orderData),//JSON.stringify把object对象转换为json格式的字符串
    dataType: "html",success: function (html) {
        //handle...
    }
});

3. 服务端代码

@RequestMapping(method = RequestMethod.POST,value = "/siteOrderDetail",headers = { "Accept=application/json;charset=utf-8" })
public String toSiteOrderDetail(@RequestBody SiteUpdateStatusForm siteOrderForm) {
        return "site/site_order_detail.jsp";
}

public class SiteUpdateStatusForm {
    private String bookDate;
    private int siteStatus;
    private int siteType;
    private int sportType;
    private List<SiteBookingCart> siteBookingCarts;
    ...
}

public class SiteBookingCart {
    private int siteID;
    private String siteName;
    private int hour;
    ...
}

完毕。

总结:
1. 如果post的数据不加JSON.stringify转换,post数据在传输时是格式这样的:

bookDate=2015-11-23&siteType=0&siteStatus=0&sportType=3&siteBookingCarts%5B0%5D%5BsiteID%5D=338&siteBookingCarts%5B0%5D%5BsiteName%5D=1%E5%8F%B7%E5%9C%BA%E5%9C%B0&siteBookingCarts%5B0%5D%5Bhour%5D=18&siteBookingCarts%5B0%5D%5Bprice%5D=40&siteBookingCarts%5B1%5D%5BsiteID%5D=338&siteBookingCarts%5B1%5D%5BsiteName%5D=1%E5%8F%B7%E5%9C%BA%E5%9C%B0&siteBookingCarts%5B1%5D%5Bhour%5D=19&siteBookingCarts%5B2%5D%5BsiteID%5D=339&siteBookingCarts%5B2%5D%5BsiteName%5D=2%E5%8F%B7%E5%9C%BA%E5%9C%B0&siteBookingCarts%5B2%5D%5Bhour%5D=19&siteBookingCarts%5B3%5D%5BsiteID%5D=339&siteBookingCarts%5B3%5D%5BsiteName%5D=2%E5%8F%B7%E5%9C%BA%E5%9C%B0&siteBookingCarts%5B3%5D%5Bhour%5D=20

那么上述方式会导致服务端解析错误,类似这样:

org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Unexpected character ('b' (code 98)): expected a valid value (number,String,array,object,'true','false' or 'null')

如果使用了JSON.stringify,则数据格式是这样的:

{"bookDate":"2015-11-23","siteType":0,"siteStatus":0,"sportType":3,"siteBookingCarts":[{"siteID":343,"siteName":"6号场地","hour":19},{"siteID":343,"hour":20},{"siteID":344,"siteName":"7号场地","hour":20}]}
