        <!-- 后缀 -->
        <propertyname="suffix"value=".jsp"/>
    </bean>
</beans>

　　4.在WEB-INF文件夹下创建名为jsp的文件夹，用来存放jsp视图。创建一个hello.jsp，在body中添加“Hello World”。

　　5.建立包及Controller，如下所示

　　6.编写Controller代码

1

3
4
5
6
7
8
9
@Controller
@RequestMapping("/mvc")
publicclass mvcController {
 
    @RequestMapping("/hello")
    publicString hello(){       
        return"hello";
    }
}

　　7.启动服务器，键入 http://localhost:8080/项目名/mvc/hello

　二、配置解析

　　1.Dispatcherservlet

　　DispatcherServlet是前置控制器，配置在web.xml文件中的。拦截匹配的请求，Servlet拦截匹配规则要自已定义，把拦截下来的请求，依据相应的规则分发到目标Controller来处理，是配置spring MVC的第一步。

　　2.InternalResourceViewResolver

　　视图名称解析器

　　3.以上出现的注解

　　@Controller 负责注册一个bean 到spring 上下文中

　　@RequestMapping 注解为控制器指定可以处理哪些 URL 请求

　三、SpringMVC常用注解

　　@Controller

　　负责注册一个bean 到spring 上下文中

　　@RequestMapping

　　注解为控制器指定可以处理哪些 URL 请求

　　@RequestBody

　　该注解用于读取Request请求的body部分数据，使用系统默认配置的HttpMessageConverter进行解析，然后把相应的数据绑定到要返回的对象上 ,再把HttpMessageConverter返回的对象数据绑定到 controller中方法的参数上

　　@ResponseBody

　　该注解用于将Controller的方法返回的对象，通过适当的HttpMessageConverter转换为指定格式后，写入到Response对象的body数据区

　　@ModelAttribute 　　　

　　在方法定义上使用 @ModelAttribute 注解：Spring MVC 在调用目标处理方法前，会先逐个调用在方法级上标注了@ModelAttribute 的方法

　　在方法的入参前使用 @ModelAttribute 注解：可以从隐含对象中获取隐含的模型数据中获取对象，再将请求参数 –绑定到对象中，再传入入参将方法入参对象添加到模型中 

　　@RequestParam　

　　在处理方法入参处使用 @RequestParam 可以把请求参 数传递给请求方法

　　@PathVariable

　　绑定 URL 占位符到入参

　　@ExceptionHandler

　　注解到方法上，出现异常时会执行该方法

　　@ControllerAdvice

　　使一个Contoller成为全局的异常处理类，类中用@ExceptionHandler方法注解的方法可以处理所有Controller发生的异常

　四、自动匹配参数

1
2
3
4
5
6
//match automatically
@RequestMapping("/person")
publicString toPerson(String name,doubleage){
    System.out.println(name+" "+age);
    return"hello";
}

　五、自动装箱

　　1.编写一个Person实体类

1

11
12
13

packagetest.SpringMVC.model;
 
publicclass Person {
    publicString getName() {
        returnname;
    }
    publicvoid setName(String name) {
        this.name = name;
    }
    publicint getAge() {
        returnage;
    }
    publicvoid setAge(intage) {
        this.age = age;
    }
    privateString name;
    privateint age;
     
}

　　2.在Controller里编写方法

1
2
3
4
5
6
//boxing automatically
@RequestMapping("/person1")
publicString toPerson(Person p){
    System.out.println(p.getName()+" "+p.getAge());
    return"hello";
}

　六、使用InitBinder来处理Date类型的参数

1
2
3
4
5
6
7
8
9
10
11
12
13
//the parameter was converted in initBinder
@RequestMapping("/date")
publicString date(Date date){
    System.out.println(date);
    return"hello";
}
    
//At the time of initialization,convert the type "String" to type "date"
@InitBinder
publicvoid initBinder(ServletRequestDataBinder binder){
    binder.registerCustomEditor(Date.class,newCustomDateEditor(newSimpleDateFormat("yyyy-MM-dd"),
            true));
}

　七、向前台传递参数

1
2
3
4
5
6
7
8
9
//pass the parameters to front-end
@RequestMapping("/show")
publicString showPerson(Map<String,Object> map){
    Person p =newPerson();
    map.put("p", p);
    p.setAge(20);
    p.setName("jayjay");
    return"show";
}

　　前台可在Request域中取到"p"

　八、使用Ajax调用

9
//pass the parameters to front-end using <span id="28_nwp" style="width: auto; height: auto; float: none;"><a id="28_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=ajax&k0=ajax&kdi0=0&luki=4&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" target="_blank" mpid="28" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">ajax</span></a></span>
@RequestMapping("/getPerson")
publicvoid getPerson(String name,PrintWriter pw){
    pw.write("hello,"+name);       
}
@RequestMapping("/name")
publicString sayHello(){
    return"name";
}

　　前台用下面的Jquery代码调用

1

3
4
5
6
7
$(function(){
    $("#btn").click(function(){
       $.post("<span id="25_nwp" style="width: auto; height: auto; float: none;"><a id="25_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=mvc&k0=mvc&kdi0=0&luki=10&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" target="_blank" mpid="25" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">mvc</span></a></span>/getPerson",{name:$("#name").val()},function(<span id="26_nwp" style="width: auto; height: auto; float: none;"><a id="26_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=data&k0=data&kdi0=0&luki=1&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" target="_blank" mpid="26" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">data</span></a></span>){
            alert(data);
        });
    });
});

　九、在Controller中使用redirect方式处理请求

1
2
3
4
5
//redirect
@RequestMapping("/redirect")
publicString redirect(){
    return"redirect:hello";
}

　十、文件上传

　　1.需要导入两个jar包

　　2.在SpringMVC配置文件中加入

1

<!-- upload settings -->
<beanid="multipartResolver" class="org.<span id="24_nwp"style="width: auto; height: auto; float: none;"><aid="24_nwl"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=spring&k0=spring&kdi0=0&luki=7&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"target="_blank"mpid="24"style="text-decoration: none;"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">spring</span></a></span>framework.web.multipart.commons.CommonsMultipartResolver">
    <propertyname="maxUploadSize"value="102400000"></property>
</bean>

　　3.方法代码

@RequestMapping(value="/upload",method=RequestMethod.POST)
publicString upload(HttpServletRequest req) throwsException{
    MultipartHttpServletRequest mreq = (MultipartHttpServletRequest)req;
    MultipartFile file = mreq.getFile("file");
    String fileName = file.getOriginalFilename();
    SimpleDateFormat sdf = newSimpleDateFormat("yyyyMMddHHmmss");       
    FileOutputStream fos = newFileOutputStream(req.getSession().getServletContext().getRealPath("/")+
            "upload/"+sdf.format(newDate())+fileName.substring(fileName.lastIndexOf('.')));
    fos.write(file.getBytes());
    fos.flush();
    fos.close();

publicclass <span id="21_nwp"style="width: auto; height: auto; float: none;"><a id="21_nwl"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=mvc&k0=mvc&kdi0=0&luki=10&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"target="_blank"mpid="21"style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">mvc</span></a></span>Controller1 {
    @RequestMapping(value="/param")
    publicString testRequestParam(@RequestParam(value="id") Integer id,
            @RequestParam(value="name")String name){
        System.out.println(id+" "+name);
        return"/hello";
    }   
}

@Controller
@RequestMapping("/rest")
publicclass RestController {
    @RequestMapping(value="/user/{id}",method=RequestMethod.GET)
    publicString get(@PathVariable("id") Integer id){
        System.out.println("get"+id);
        return"/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.POST)
    publicString post(@PathVariable("id") Integer id){
        System.out.println("post"+id);
        return"/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.PUT)
    publicString put(@PathVariable("id") Integer id){
        System.out.println("put"+id);
        return"/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.DELETE)
    publicString delete(@PathVariable("id") Integer id){
        System.out.println("delete"+id);
        return"/hello";
    }
     
}

　　2.form表单发送put和delete请求

　　在web.xml中配置

<!-- configure the HiddenHttpMethodFilter,convert the post method to put or delete -->
<filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.<spanid="19_nwp"style="width: auto; height: auto; float: none;"><aid="19_nwl"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=18&is_app=0&jk=e36ef11d8131b478&k=spring&k0=spring&kdi0=0&luki=7&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=78b431811df16ee3&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"target="_blank"mpid="19"style="text-decoration: none;"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">spring</span></a></span>framework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

　　在前台可以用以下代码产生请求
