hibernate 文件 res version 日誌 創建 oca skip www
1： 先創建一個maven web 項目：
可以參照之前的文章： 用Maven 創建一個 簡單的 JavaWeb 項目
創建好之後的目錄是這樣的;
2: 先配置maven 修改pom.xml
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.etoak</groupId> <artifactId>mss01</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.build.timestamp.format>yyyyMMddHHmmss</maven.build.timestamp.format> <spring.version>4.2.5.RELEASE</spring.version> <log4j.version>1.2.17</log4j.version> <slf4j.version>1.7.7</slf4j.version> </properties><dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- javaEE --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>7.0</version> </dependency> <!-- servlet start --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- servlet end --> <!-- spring start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</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>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</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>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-jpa</artifactId> <version>1.10.1.RELEASE</version> </dependency> <!-- spring end --> <!-- log4j start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.2.4.Final</version> </dependency> <!-- log4j end --> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.1</version> <configuration> <skipTests>true</skipTests> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> <finalName>mss01</finalName> <!-- 這裏是 項目名 --> </build> </project>
3: 修改web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>mss01</display-name> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 加載順序: 上下文參數 >>> 監聽器 >>> 過濾器 >>> 攔截器 --> <!-- 日誌記錄 --> <context-param> <!-- 日誌配置文件路徑 --> <param-name>log4jConfigLocation</param-name> <param-value>classpath:config/properties/log4j.properties</param-value> </context-param> <context-param> <!-- 日誌頁面的刷新間隔 --> <param-name>log4jRefreshInterval</param-name> <param-value>6000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:config/xml/application.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置靜態資源映射,防止靜態資源被攔截後導致controller返回的頁面的js,css失效 這是第一種方式 還有一個方式在spring-mvc.xml中 --> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> <url-pattern>*.css</url-pattern> <url-pattern>/assets/*"</url-pattern> <url-pattern>/images/*</url-pattern> </servlet-mapping> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:config/xml/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 設置session 存活時長 60 min --> <session-config> <session-timeout>60</session-timeout> </session-config> </web-app>
4: 根據web.xml 添加一些文件:
再添加文件之前先來一張添加好之後的項目架構:
下面是: application.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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "> <!-- 上面沒有帶上版本號 系統會自動匹配合適的 --> <!-- 采用註釋的方式配置bean --> <context:annotation-config /> <!-- 自動掃描註解 --> <context:component-scan base-package="com.etoak.mssm" /> <!-- 因為是簡單的maven Spring SpringMvc 項目 所以 也就沒有配置 數據源之類的; --> </beans>
下面是: sring-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: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" > <!-- 上面沒有帶上版本號 系統會自動匹配合適的 --> <!-- 開啟註解模式驅動 --> <mvc:annotation-driven></mvc:annotation-driven> <!-- 自動掃描web包 ,將帶有註解的類 納入spring容器管理 --> <context:component-scan base-package="com.etoak.mss"/> <!-- 視圖解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 默認的註解映射的支持 --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/plain;charset=utf-8</value> <value>application/json;charset=utf-8</value> <value>application/x-www-form-urlencoded</value> </list> <!-- 設置 這些是為了 IE 瀏覽器 ajax 請求返回 json時 變成下載 --> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!--配置靜態資源映射,防止靜態資源被攔截後導致controller返回的頁面的js,css失效 這是第二種方式 還有一種方式在web.xml中 --> <!-- <mvc:resources location="/static/css/" mapping="/css/**"></mvc:resources> <mvc:resources location="/static/js/" mapping="/js/**"></mvc:resources> <mvc:resources location="/static/images/" mapping="/images/**"/> --> </beans>
為了體現出spring mvc 的作用 寫了兩個jsp頁面 (index.jsp 和 welcome.jsp);
其中 index.jsp 放置在webapp 目錄下面 可以直接訪問 ; welcome.jsp放置在 WEB-INF 目錄下面 只能通過 controller 跳轉來訪問.
先來張圖:
下面是index.jsp的代碼:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; String welcomePagePath = basePath+"index/welcome"; %> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Index Page</title> </head> <body> This is index page . <br/> <br/> <a href="<%=welcomePagePath %>"> Click on me to go to welcome page . </a> </body> </html>
這是 welcome.jsp的代碼
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Welcome Page </title> </head> <body> This is welcome page . </body> </html>
下面就是處理請求,控制跳轉的controller了
package com.etoak.mss.welcome.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping(value="/index") public class WelcomeController { @RequestMapping(value="/welcome",method=RequestMethod.GET) public String welcome(){ System.out.println("進來了!"); return "welcome"; } }
ok 至此 整個項目 已經搭建完成:
先進行兩個Maven 操作:clean 和 install ;
然後再在tomcat 上運行;
是不是看到下面的頁面?
控制臺 也打印了
好了 上面就是 maven 和 Spring SpringMvc 的整合 ;
接下來 準備再寫一個 maven spring spring Mvc mybatis 整合項目;
