本篇文章給大家分享的是有關(guān)如何在AngularJs中結(jié)合SpringMVC使用,小編覺得挺實(shí)用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
首先我們把springmvc的環(huán)境搭好,先來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_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SpringMVC</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/AngularJSTestApplicationContext.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>baobaotao</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/AngularJSTestApplicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>baobaotao</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
這里我把a(bǔ)pplicationContext改了一個(gè)名字,以免和我自己本身用的沖突,并且設(shè)置了一下觸發(fā)springmvc的url模式,是以.do結(jié)尾發(fā)起請(qǐng)求
下面是AngularJSTestApplicationContext.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:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <mvc:annotation-driven /> <context:component-scan base-package="com.baobaotao.web"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
我直接用了<mvc:annotation-driven /> 就用默認(rèn)的數(shù)據(jù)轉(zhuǎn)換器了,因?yàn)槟J(rèn)的里面有對(duì)Json串進(jìn)行數(shù)據(jù)綁定的轉(zhuǎn)換器
這樣mvc的環(huán)境已經(jīng)搭建好了,下面我們寫頁面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html ng-app=""> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript" src="../angular.js"></script> <title>AngularJSTest</title> </head> <body ng-controller="MyController"> <p>User</p> <p>ID</p> <input id="id" name="id" ng-model="saveUser.id"> <br> <p>Name</p> <input id="id" name="name" ng-model="saveUser.name"> <br> <p>age</p> <input id="id" name="age" ng-model="saveUser.age"> <br> <button ng-click="getUser()">提交</button> <script> function MyController($scope, $http){ $scope.saveUser = { id:1, name:"John", age:"16" }; $scope.getUser = function(){ $http({ method: "POST", url: "http://localhost:8080/SpringMVC/AngularJS/getUser.do", data: $scope.saveUser }).success(function (data, status){ // handle success }) }; } </script> </body> </html>
頁面很簡單,有三個(gè)輸入?yún)?shù),id,name,age綁定了控制器里面的saveUser對(duì)象的屬性,這個(gè)也對(duì)應(yīng)了我后臺(tái)需要綁定的數(shù)據(jù)的屬性名稱。對(duì)于AngularJs,在body標(biāo)簽處聲明了一個(gè)控制器MyController,之后在script中對(duì)這個(gè)控制器里面的saveUser 對(duì)象屬性進(jìn)行了初始化并且定義了一個(gè)方法getUser,它是傳遞參數(shù)的關(guān)鍵。之后制定了當(dāng)點(diǎn)擊提交按鈕以后會(huì)把數(shù)據(jù)傳遞出去。
看一下getUser方法,看上去很像ajax的提交數(shù)據(jù)方式,指定了請(qǐng)求的方法是Post,請(qǐng)求的地址url以及請(qǐng)求中要發(fā)送的數(shù)據(jù)data,這里我將MyController控制器中的對(duì)象屬性作為數(shù)據(jù)進(jìn)行傳遞,這個(gè)對(duì)象在傳輸?shù)臅r(shí)候會(huì)自動(dòng)的將其結(jié)構(gòu)轉(zhuǎn)換成Json格式進(jìn)行傳遞
下面貼上后臺(tái)Controller的代碼
package com.baobaotao.web; import com.baobaoto.domain.AngularUser; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.servlet.ModelAndView; @Controller @RequestMapping(value="/AngularJS") public class TestAngularJS { @RequestMapping("/intro.do") public ModelAndView intro(){ ModelAndView mav = new ModelAndView(); mav.setViewName("AngularJsTest"); return mav; } @RequestMapping(value="/getUser.do", method=RequestMethod.POST) public String getUser(@RequestBody AngularUser angularUser){ System.out.println("ID" + angularUser.getId()); System.out.println("name" + angularUser.getName()); System.out.println("age" + angularUser.getAge()); return null; } }
頁面上的請(qǐng)求映射到了這里的getUser方法,因?yàn)轫撁嫔咸岢龅恼?qǐng)求方法是post,所以我們這里也設(shè)定RequestMapping的method為post,最為關(guān)鍵的就是@RequestBody這個(gè)注釋,其可以將傳來的Json格式的數(shù)據(jù)與Bean中的屬性值進(jìn)行直接綁定,也就是說這里的AngularUser 對(duì)象內(nèi)的屬性已經(jīng)成功的被賦值了,這里貼上AngularUser Bean定義
package com.baobaoto.domain; public class AngularUser { Long id; String name; String age; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } }
部署到服務(wù)器上運(yùn)行,直接點(diǎn)擊提交按鈕以后后臺(tái)控制臺(tái)結(jié)果
ID1
nameJohn
age16
之后我們將input中的數(shù)值改變?yōu)?、David、17,點(diǎn)擊提交按鈕控制臺(tái)結(jié)果
ID2
nameDavid
age17
測(cè)試成功
從后臺(tái)獲取數(shù)據(jù)
這個(gè)要容易些,對(duì)原有的內(nèi)容適當(dāng)修改就可以了
頁面
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html ng-app=""> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript" src="../angular.js"></script> <title>AngularJSTest</title> </head> <body ng-controller="MyController"> <p>User</p> <p>ID</p> <input id="id" name="id" ng-model="saveUser.id"> <br> <p>Name</p> <input id="id" name="name" ng-model="saveUser.name"> <br> <p>age</p> <input id="id" name="age" ng-model="saveUser.age"> <br> <ul> <li ng-repeat="x in infos"> {{ x.ID + x.name + x.age }} </li> </ul> <button ng-click="getUser()">提交</button> <script> function MyController($scope, $http){ $scope.saveUser = { id:1, name:"John", age:"16" }; $scope.getUser = function(){ $http({ method: "POST", url: "http://localhost:8080/SpringMVC/AngularJS/getUser.do", data: $scope.saveUser }).success(function (data){ $scope.infos = data; }) }; } </script> </body> </html>
這里增加了一個(gè)ul標(biāo)簽用來接收從后臺(tái)傳過來的數(shù)據(jù),里面存儲(chǔ)的是一個(gè)Json數(shù)組,這個(gè)數(shù)組在當(dāng)我們點(diǎn)擊按鈕之后觸發(fā)的回調(diào)函數(shù)中進(jìn)行賦值,而回調(diào)的這個(gè)函數(shù)的參數(shù)data就是我們從后臺(tái)獲取到的數(shù)據(jù),具體data是怎樣的要看后臺(tái)Controller中返回的數(shù)值是怎樣的。這里我們返回的是一個(gè)Json數(shù)組
package com.baobaotao.web; import com.baobaoto.domain.AngularUser; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.servlet.ModelAndView; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; @Controller @RequestMapping(value="/AngularJS") public class TestAngularJS { @RequestMapping("/intro.do") public ModelAndView intro(){ ModelAndView mav = new ModelAndView(); mav.setViewName("AngularJsTest"); return mav; } @RequestMapping(value="/getUser.do", method=RequestMethod.POST) @ResponseBody public List<Map<String, String>> getUser(@RequestBody AngularUser angularUser){ System.out.println("ID" + angularUser.getId()); System.out.println("name" + angularUser.getName()); System.out.println("age" + angularUser.getAge()); List<Map<String, String>> list = new ArrayList<Map<String, String>>(); for(int i = 0; i < 5; i++){ Map<String, String> map = new HashMap<String, String>(); map.put("ID", String.valueOf(i)); map.put("name", String.valueOf(i)); map.put("age", String.valueOf(i)); list.add(map); } return list; } }
上面是修改過的Controller,我將返回值改為了一個(gè)list,里面的數(shù)據(jù)是Map這樣就剛好符合Json數(shù)組的數(shù)據(jù)模式了,當(dāng)然最重要的是這里在方法前需要添加一個(gè)@ResponseBody 注釋,它可以把返回的值轉(zhuǎn)化為Json格式的數(shù)據(jù)
好了,運(yùn)行一下程序試試,點(diǎn)擊提交按鈕,出現(xiàn)了結(jié)果
測(cè)試成功
上面這兩種是最簡單的方式實(shí)現(xiàn)了AngularJs和springmvc的結(jié)合使用,基本的功能算是實(shí)現(xiàn)了
