SPRING MVC3.2案例讲解--SPRING MVC3的各种URL映射(2)

继续上一章节，亲们没事留个言，对我是个鼓励，俺就把更有动力这个学习笔记继续下去！！！

 

JAVA代码如下：

@Controllerpublic class MappingController {//对应的URL 只能是 /mapping/path@RequestMapping("/mapping/path")public @ResponseBody String byPath() {return "Mapped by path!";}// 对应的URL 可以是/mapping/path/abc,也可以是/mapping/path/def ;//  /mapping/path/* ：*对应任意字符串@RequestMapping(value="/mapping/path/*", method=RequestMethod.GET)public @ResponseBody String byPathPattern(HttpServletRequest request) {return "Mapped by path pattern ('" + request.getRequestURI() + "')";}//对应的URL是/mapping/method，但必须是GET方式提交请求@RequestMapping(value="/mapping/method", method=RequestMethod.GET)public @ResponseBody String byMethod() {return "Mapped by path + method";}//对应URL是/mapping/parameter?foo=bar ,即URL链接后必须带有foo参数@RequestMapping(value="/mapping/parameter", method=RequestMethod.GET, params="foo")public @ResponseBody String byParameter() {return "Mapped by path + method + presence of query parameter!";}//对应URL是/mapping/parameter ,即URL链接后必须不带有foo参数，但可以是其他参数@RequestMapping(value="/mapping/parameter", method=RequestMethod.GET, params="!foo")public @ResponseBody String byParameterNegation() {return "Mapped by path + method + not presence of query parameter!";}//  /mapping/header必须是GET提交，并且必须带有requestHeader(FooHeader=foo)；见 js代码片段1@RequestMapping(value="/mapping/header", method=RequestMethod.GET, headers="FooHeader=foo")public @ResponseBody String byHeader() {return "Mapped by path + method + presence of header!";}// 这个就是和上面相反的，@RequestMapping(value="/mapping/header", method=RequestMethod.GET, headers="!FooHeader")public @ResponseBody String byHeaderNegation() {return "Mapped by path + method + absence of header!";}//  /mapping/consumes 必须是POST 提交 ；contentType必须是: "application/json" ；consumes（消费者）表示用户需要提交的数据类型为JSON

//见JS代码片段1@RequestMapping(value="/mapping/consumes", method=RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE)public @ResponseBody String byConsumes(@RequestBody JavaBean javaBean) {return "Mapped by path + method + consumable media type (javaBean '" + javaBean + "')";}// /mapping/produces 必须是GET提交，produces(生产者)，表示返回给用户的数据类型，本例是JAVABEAN转化成JSON数据@RequestMapping(value="/mapping/produces", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)public @ResponseBody JavaBean byProducesJson() {return new JavaBean();}// 类似于上面的@RequestMapping(value="/mapping/produces", method=RequestMethod.GET, produces=MediaType.APPLICATION_XML_VALUE)public @ResponseBody JavaBean byProducesXml() {return new JavaBean();}}

 

  js代码片段1

 $("#byHeader").click(function(){var link = $(this);

$.ajax({ url: this.href, dataType: "text", beforeSend: function(req) { req.setRequestHeader("FooHeader", "foo"); }, success: function(form) { MvcUtil.showSuccessResponse(form, link); }, error: function(xhr) { MvcUtil.showErrorResponse(xhr.responseText, link); }});return false;});

$.ajax({ type: "POST", url: form.attr("action"), data: data, contentType: "application/json", dataType: "text", success: function(text) { MvcUtil.showSuccessResponse(text, button); }, error: function(xhr) { MvcUtil.showErrorResponse(xhr.responseText, button); }});return false;
