springMVC專案建立
阿新 • • 發佈：2018-11-12
結合maven一起使用，首先通過File-->new-->Maven Project建立maven專案，
點選Finish完成建立。
建立後目錄結構如下：
pom.xml中儲存的是maven依賴，從而匯入相關jar包。
在src中建立如下目錄結構：
pom.xml檔案內容如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>QC2</groupId> <artifactId>learn_01</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>learn_01 Maven Webapp</name> <url>http://maven.apache.org</url> <!-- 指明編譯原始碼時使用的字元編碼，maven編譯的時候預設使用的GBK編碼， 通過project.build.sourceEncoding屬性設定字元編碼，告訴maven這個專案使用UTF-8來編譯 --> <properties> <!-- Spring版本號 --> <spring.version>4.3.8.RELEASE</spring.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>6.0.6</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <!-- Spring相關包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- AOP相關包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.0</version> </dependency> <!-- MyBatis相關包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- MySQL相關包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.26</version> </dependency> <!-- 資料庫連線池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!-- Spring整合MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!-- JSP標準標籤庫 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <scope>compile</scope> </dependency> <!-- gson json轉換包 --> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.5</version> </dependency> <!-- 日誌相關包 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.21</version> </dependency> <!-- 新增poi相關的jar包 上傳excel檔案 --> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.8</version> <exclusions> <exclusion> <artifactId>commons-codec</artifactId> <groupId>commons-codec</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.8</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.1</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-io/commons-io --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <!-- 新增郵件傳送的依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>5.0.0.RELEASE</version> </dependency> <!--郵件傳送--> <dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.6.1</version> </dependency> </dependencies> <build> <finalName>learn_01</finalName> </build> </project>
web.xml內容如下：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>Dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
spring-mvc.xml如下：
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 啟動自動掃描 --> <context:component-scan base-package="com.qc2" /> <!-- 註冊MVC註解驅動 --> <mvc:annotation-driven /> <!-- 靜態資源可訪問的設定方式 --> <mvc:default-servlet-handler /> <!-- 配置檢視解析器，可以顯式設定，也可以不設定，不設定會依據SpringMVC的預設設定 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/views/" /> <property name="suffix" value=".jsp" /> </bean> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8"></property> <property name="maxUploadSize" value="10485760000"></property> <property name="maxInMemorySize" value="40960"></property> </bean> </beans>
建立TestController.java如下：
package com.qc2.controllers;
import java.util.List;
import org.springframework.stereotype.Controller;
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 com.google.gson.Gson;
@Controller
public class TestContorller {
@ResponseBody
@RequestMapping(value ="views/hello", produces = "application/json;charset=utf-8",method ={RequestMethod.GET})
public String hello(String age){
Gson gson =new Gson();
String json =gson.toJson(age);
return json;
}
@RequestMapping(value ="views/hello2", produces = "application/json;charset=utf-8",method ={RequestMethod.GET})
public ModelAndView hello2(String name){
ModelAndView mv = new ModelAndView();
mv.addObject("message","ooooooooooooooo");
mv.setViewName("h2");
return mv;
}
}
建立Test.jsp如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js">
</script>
<title>Insert title here</title>
</head>
<body>
<div >
ss
</div>
<script>
var data2={
"age":"jhkvhvjgj"
};
$.ajax({
type:"get",
url: "http://localhost:8080/learn_01/views/hello",
data: data2,
cache: false,
async : false,
success: function (data ,textStatus, jqXHR)
{
alert(data);
},
error:function (XMLHttpRequest, textStatus, errorThrown) {
alert("456");
}
});
</script>
</body>
</html>執行結果如下：
