SpringMVC---RequestMappingAnt 路径PathVariable 注解HiddenHttpMethodFilter 过滤器用 POJO 作为参数 _requestmapping

犀渠玉剑良家子，白马金羁侠少年。这篇文章主要讲述SpringMVC---RequestMappingAnt 路径PathVariable 注解HiddenHttpMethodFilter 过滤器用 POJO 作为参数相关的知识，希望能为你提供帮助。
一、web.xml

< ?xml version="1.0" encoding="UTF-8"?> < web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> < display-name> SpringMVC_001_001< /display-name> < welcome-file-list> < welcome-file> index.html< /welcome-file> < welcome-file> index.htm< /welcome-file> < welcome-file> index.jsp< /welcome-file> < welcome-file> default.html< /welcome-file> < welcome-file> default.htm< /welcome-file> < welcome-file> default.jsp< /welcome-file> < /welcome-file-list> < !-- 配置 DispatcherServlet --> < servlet> < !-- springDispatcherServlet 在应用启动的时候被创建，不是调用的时候被创建。 --> < !-- 实际上也可以不通过 contextConfigLocation 来配置 springmvc 的配置文件，而使用默认的。 --> < !-- 默认的配置文件为：/WEB-INF/< servlet-name> -servlet.xml --> < !-- 把 SRC 下的 spring-mvc.xml 移动在/WEB-INF/下并改名为 springDispatcherServlet-servlet.xml的文件，并注释 R20~R23 --> < !--配置 DispatcherServlet 初始化参数，作用是配置 SpringMVC 配置文件的位置和名称--> < servlet-name> springDispatcherServlet< /servlet-name> < servlet-class> org.springframework.web.servlet.DispatcherServlet< /servlet-class> < init-param> < param-name> contextConfigLocation< /param-name> < param-value> classpath:spring-mvc.xml< /param-value> < /init-param> < load-on-startup> 1< /load-on-startup> < /servlet> < !-- 将所有请求映射到DispatcherServlet处理 --> < servlet-mapping> < !--配置 DispatcherServlet 初始化参数，作用是配置 SpringMVC 配置文件的位置和名称--> < servlet-name> springDispatcherServlet< /servlet-name> < url-pattern> /< /url-pattern> < /servlet-mapping> < !-- 配置HiddenHttpMethodFilter，可以把POST请求转换为DELETE或PUT请求 --> < filter> < filter-name> hiddenHttpMethodFilter< /filter-name> < filter-class> org.springframework.web.filter.HiddenHttpMethodFilter< /filter-class> < /filter> < filter-mapping> < filter-name> hiddenHttpMethodFilter< /filter-name> < url-pattern> /*< /url-pattern> < /filter-mapping> < /web-app>

二、HelloWorld.java

package com.chinasofti.springmvc.handlers; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import com.chinasofti.springmvc.entity.User; @Controller @RequestMapping(value="https://www.songbingjia.com/springmvc") public class HelloWorld { /** * 1、使用 RequestMapping 注解来映射请求的 URL(统一资源定位) * 2、返回值会通过视图解析器解析为实际的物理视图，对于 InternalResourceViewResolver 而言， * 视图解析器会做如下的解析： * 2.1、通过 prefix + returnVal + 后缀这样的方式得到实际的物理视图，然后做转发操作。 * 如：/WEB-INF/views/success.jsp * @return */public static final String SUCCESS="success"; /* * 测试跳换页面 */ @RequestMapping("/helloword") public String hello(){ System.out.println("hello word"); return SUCCESS; }/* * 测试Post提交 */ @RequestMapping(value="https://www.songbingjia.com/helloword",method=RequestMethod.POST) public String testPost(){ System.out.println("hello word"); return SUCCESS; }/* * 测试Params参数 params表示要传递的参数，username表示传递的第一个参数，值不确定，第二个参数是 age并且年龄不能是等于10的 * */ @RequestMapping(value="https://www.songbingjia.com/android/testParamaAndHeaders",params={"username","age!=10"}, headers={"Accept-Language=zh-CN,zh; q=0.8,en-US; q=0.5,en; q=0.3"}) public String testParamaAndHeaders(){ System.out.println("testParamaAndHeaders"); return SUCCESS; }/* * 测试Ant格式请求路径 * */ @RequestMapping(value="https://www.songbingjia.com/android/testAnt/*/abc",params={"username","age!=10"}, headers={"Accept-Language=zh-CN,zh; q=0.8,en-US; q=0.5,en; q=0.3"}) public String testAnt(){ System.out.println("testAntPath"); return SUCCESS; }/* * @PathVariable可以映射URL中的占位符到目标方法中 */ @RequestMapping("/testPathVariable/{id}") public String testPathVariable(@PathVariable("id") Integer id){ System.out.println("testPathVariable:"+id); return SUCCESS; }/* *测试GET方法 --------------》查 */ @RequestMapping(value = "https://www.songbingjia.com/testRest/{id}", method = RequestMethod.GET) public String testRest(@PathVariable Integer id) { System.out.println("testRest GET:" + id); return SUCCESS; }// POST是新增，没有参数。------》增 @RequestMapping(value = "https://www.songbingjia.com/testRest", method = RequestMethod.POST) public String testRest() { System.out.println("testRest POST"); return SUCCESS; } /* * 测试DELETE方法-----------》删 */ @RequestMapping(value = "https://www.songbingjia.com/testRest/{id}", method = RequestMethod.DELETE) public String testDeleteRest(@PathVariable Integer id) { System.out.println("testRest DELETE:" + id); return SUCCESS; } /* * 测试PUT方法--------------》改 */ @RequestMapping(value = "https://www.songbingjia.com/testRest/{id}", method = RequestMethod.PUT) public String testPutRest(@PathVariable Integer id) { System.out.println("testRest PUT:" + id); return SUCCESS; }/* * 测试POJO */ @RequestMapping("/testPojo") public String testPojo(User user){ System.out.println(user.getUsername()+"\t"+user.getPassword()+"\t"+user.getEmail()+"\t"+user.getAge() +"\t"+user.getAddress().getProvince()+"\t"+user.getAddress().getCity()); return SUCCESS; }/* * 使用 Servlet 原生 API 作为参数 ***HttpServletRequest ***HttpServletResponse ***HttpSession *Java.security.Principal *Locale *InputStream *OutputStream *Reader *Writer */ @RequestMapping("/testServletAPI") public String testServletAPI(HttpServletRequest request,HttpServletResponse response){ System.out.println("ServletAPI:"+request+"\t\r"+response); return SUCCESS; } }

三、Address 类

package com.chinasofti.springmvc.entity; public class Address { private String province; private String city; public String getProvince() { return province; } public void setProvince(String province) { this.province = province; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } @Override public String toString() { return "Address [province=" + province + ", city=" + city + "]"; } }

User类

package com.chinasofti.springmvc.entity; public class User { private String username; private String password; private String email; private Integer age; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; }public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; }private Address address; public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } @Override public String toString() { return "User [username=" + username + ", password=" + password + ", email=" + email + ", age=" + age + ", address=" + address + "]"; } }

四、spring-mvc.xml

< ?xml version="1.0" encoding="UTF-8"?> < beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> < !-- 配置自动扫描的包 --> < context:component-scan base-package="com.chinasofti"> < /context:component-scan> < !-- 配置视图解析器：如何把 handler 方法返回值解析为实际的物理视图 --> < bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> < property name="prefix" value="https://www.songbingjia.com/WEB-INF/views/"> < /property> < property name="suffix" value="https://www.songbingjia.com/android/.jsp"> < /property> < /bean> < /beans>
