<!-- 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
2
3
4
5
6
7
8
9
@Controller
@RequestMapping("/mvc")
publicclassmvcController {

@RequestMapping("/hello")
publicString hello(){
return"hello";
}
}
　　7.启动服务器，键入 http://localhost:8080/项目名/ href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&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=337cc2297d4cb4e&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>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
2
3
4
5

7
8
9
10
11
12
13
14

packagetest.SpringMVC.model;

publicclassPerson {
publicString getName() {
returnname;
}
publicvoidsetName(String name) {
this.name = name;
}
publicintgetAge() {
returnage;
}
publicvoidsetAge(intage) {
this.age = age;
}
privateString name;
privateintage;

}
　　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

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 <span style="width: auto; height: auto; float: none;" id="38_nwp"><a style="text-decoration: none;" mpid="38" target="_blank" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=type&k0=type&kdi0=0&luki=6&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" id="38_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">type</span></a></span> "String" to type "date"
@InitBinder
publicvoidinitBinder(ServletRequestDataBinder binder){
binder.registerCustomEditor(Date.class, <span style="width: auto; height: auto; float: none;"id="39_nwp"><a style="text-decoration: none;"mpid="39"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=new&k0=new&kdi0=0&luki=1&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="39_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">new</span></a></span> CustomDateEditor(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 =<span style="width: auto; height: auto; float: none;"id="37_nwp"><a style="text-decoration: none;"mpid="37"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=new&k0=new&kdi0=0&luki=1&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="37_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">new</span></a></span> Person();
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

1

3
4
5
6
7
8
9
//pass the parameters to front-end using <span style="width: auto; height: auto; float: none;" id="36_nwp"><a style="text-decoration: none;" mpid="36" target="_blank" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=ajax&k0=ajax&kdi0=0&luki=3&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" id="36_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">ajax</span></a></span>
@RequestMapping("/getPerson")
publicvoidgetPerson(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
2
3
4
5
6
7
$(function(){
$("#btn").click(function(){
$.post("<span style="width: auto; height: auto; float: none;" id="34_nwp"><a style="text-decoration: none;" mpid="34" target="_blank" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=mvc&k0=mvc&kdi0=0&luki=10&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0" id="34_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">mvc</span></a></span>/getPerson",{name:$("#name").val()},function(data){
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

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);

u.setId(1);
u.setName("jayjay");
u.setBirth(newDate());
returnu;
}
}

　十四、异常的处理

　　1.处理局部异常（Controller内）

11
12
13
@ExceptionHandler
publicModelAndView exceptionHandler(Exception ex){
ModelAndView mv =newModelAndView("error");
mv.addObject("exception", ex);
System.out.println("in testExceptionHandler");
returnmv;
}

@RequestMapping("/error")
publicString error(){
inti =5/0;
return"hello";
}
　　2.处理全局异常（所有Controller）

9
10
@ControllerAdvice
publicclasstestControllerAdvice {
@ExceptionHandler
publicModelAndView exceptionHandler(Exception ex){

mv.addObject("exception", ex);
System.out.println("in testControllerAdvice");
returnmv;
}
}
　　3.另一种处理全局异常的方法

　　在SpringMVC配置文件中配置

2
3
4
5
6
7
8
<!-- configure SimpleMappingExceptionResolver -->
<beanclass="org.<span style="width: auto; height: auto; float: none;"id="20_nwp"><astyle="text-decoration: none;"mpid="20"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&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=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="20_nwl"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">spring</span></a></span>framework.web.<spanstyle="width: auto; height: auto; float: none;"id="21_nwp"><astyle="text-decoration: none;"mpid="21"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=servlet&k0=servlet&kdi0=0&luki=5&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="21_nwl"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">servlet</span></a></span>.handler.SimpleMappingExceptionResolver">
<propertyname="exceptionMappings">
<props>
<propkey="java.lang.ArithmeticException">error</prop>
</props>
</property>
</bean>
　　error是出错页面

　十五、设置一个自定义拦截器

　　1.创建一个MyInterceptor类，并实现HandlerInterceptor接口

publicclassMyInterceptorimplementsHandlerInterceptor {

@Override
publicvoidafterCompletion(HttpServletRequest arg0,
HttpServletResponse arg1, Object arg2, Exception arg3)
throwsException {
System.out.println("afterCompletion");
}

@Override
publicvoidpostHandle(HttpServletRequest arg0, HttpServletResponse arg1,
Object arg2, ModelAndView arg3)throwsException {
System.out.println("postHandle");
}

@Override
publicbooleanpreHandle(HttpServletRequest arg0, HttpServletResponse arg1,
Object arg2)throwsException {
System.out.println("preHandle");
returntrue;
}

}
　　2.在SpringMVC的配置文件中配置

1
2
3
4
5
6
7
<!-- interceptor setting -->
<<spanstyle="width: auto; height: auto; float: none;"id="19_nwp"><astyle="text-decoration: none;"mpid="19"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&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=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="19_nwl"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">mvc</span></a></span>:interceptors>
<mvc:interceptor>
<mvc:mappingpath="/mvc/**"/>
<beanclass="test.SpringMVC.Interceptor.MyInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
　　3.拦截器执行顺序



　十六、表单的验证（使用Hibernate-validate）及国际化

　　1.导入Hibernate-validate需要的jar包



(未选中不用导入)



　　2.编写实体类User并加上验证注解

publicclassUser {
publicintgetId() {
returnid;
}
publicvoidsetId(intid) {
this.id = id;
}
publicString getName() {
returnname;
}
publicvoidsetName(String name) {
this.name = name;
}
publicDate getBirth() {
returnbirth;
}
publicvoidsetBirth(Date birth) {
this.birth = birth;
}
@Override
publicString toString() {
return"User [id="+ id +", name="+ name +", birth="+ birth +"]";
}
privateintid;
@NotEmpty
privateString name;

@Past
@DateTimeFormat(pattern="yyyy-MM-dd")
privateDate birth;
}
　　ps:@Past表示时间必须是一个过去值

　　3.在jsp中使用SpringMVC的form表单

1
2
3
4
5
6
<form:formaction="form/add"method="post"modelAttribute="user">
id:<form:inputpath="id"/><form:errorspath="id"/><br>
name:<form:inputpath="name"/><form:errorspath="name"/><br>
birth:<form:inputpath="birth"/><form:errorspath="birth"/>
<input<spanstyle="width: auto; height: auto; float: none;"id="17_nwp"><astyle="text-decoration: none;"mpid="17"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=type&k0=type&kdi0=0&luki=6&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="17_nwl"><spanstyle="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">type</span></a></span>="submit" value="submit">
</form:form>
　　ps:path对应name

　　4.Controller中代码

@Controller
@RequestMapping("/form")
publicclassformController {
@RequestMapping(value="/add",method=RequestMethod.POST)
publicString add(@ValidUser u,BindingResult br){
if(br.getErrorCount()>0){
return"addUser";
}
return"showUser";
}

@RequestMapping(value="/add",method=RequestMethod.GET)
publicString add(Map<String,Object> map){
map.put("user",<span style="width: auto; height: auto; float: none;"id="16_nwp"><a style="text-decoration: none;"mpid="16"target="_blank"href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=20&is_app=0&jk=4ecbd49722cc3703&k=new&k0=new&kdi0=0&luki=1&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=337cc2297d4cb4e&ssp2=1&stid=9&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F6436%2Ehtml&urlid=0"id="16_nwl"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">new</span></a></span> User());
return"addUser";
}
}
　　ps:

　　1.因为jsp中使用了modelAttribute属性，所以必须在request域中有一个"user".

　　2.@Valid 表示按照在实体上标记的注解验证参数

　　3.返回到原页面错误信息回回显，表单也会回显

　　5.错误信息自定义

　　在src目录下添加locale.properties

NotEmpty.user.name=name can't not be empty
Past.user.birth=birth should be a past value
DateTimeFormat.user.birth=the format of input is wrong typeMismatch.user.birth=the format of input is wrong
typeMismatch.user.id=the format of input is wrong

　　在SpringMVC配置文件中配置

<propertyname="basename"value="locale"></property>
</bean>
　　6.国际化显示

　　在src下添加locale_zh_CN.properties

username=账号
password=密码

　　locale.properties中添加

username=user name
password=password

　　创建一个locale.jsp

<body>
<fmt:messagekey="username"></fmt:message>
<fmt:messagekey="password"></fmt:message>
</body>
　　在SpringMVC中配置

　　让locale.jsp在WEB-INF下也能直接访问

　　最后，访问locale.jsp，切换浏览器语言，能看到账号和密码的语言也切换了

　十七、压轴大戏--整合SpringIOC和SpringMVC

　　1.创建一个test.SpringMVC.integrate的包用来演示整合，并创建各类



　　2.User实体类

　十八、SpringMVC详细运行流程图



　十九、SpringMVC与struts2的区别

　　1、springmvc基于方法开发的，struts2基于类开发的。springmvc将url和controller里的方法映射。映射成功后 springmvc生成一个Handler对象，对象中只包括了一个method。方法执行结束，形参数据销毁。springmvc的 controller开发类似web service开发。

　　2、springmvc可以进行单例开发，并且建议使用单例开发，struts2通过类的成员变量接收参数，无法使用单例，只能使用多例。

　　3、经过实际测试，struts2速度慢，在于使用struts标签，如果使用struts建议使用jstl。
