Spring MVC 的配置安装

这个是李绪成老师今天布置的作业,我顺便做了个教程欢迎大家交流。首先祝大家女神节快乐!(2016,3,8)

一、首先你要准备Eclipse开发环境:

至于Jdk的环境变量请自行百度、谷歌,里面的教程非常详细。

Eclipse软件请自行去百度或谷歌下载!配好Eclipse环境就该我们大显身手了!请继续往下看,,,(作为程序员这个都还不会,你想干啥?你咋不飞呢!)

1.打开Eclipse,点击File-->new,弹出窗口选择Web-->Dynamic web project.

2.一直next,在新窗口中输入项目名称,然后继续next,最后finish。项目列表中就有你输入名称的项目了!

3.导入Spring MVC相关的JAR包到lib下,首先下载jar包。

解压缩后直接将jar文件复制粘贴到WebContent目录下的WEB-INF目录里的lib目录里。

4.配置项目引用刚才导入到lib下的jar包。

右键点击项目名,在菜单中选择Build Path-->Configuration build path...

二、新增Spring MVC的配置文件:

找到项目目录下的Java Resources,右键点击Java Resources,在弹出窗口选择new-->source folder.

source folder建好之后,需要把配置好文件复制粘贴进去

这四个文件的说明:

database.properties:配置数据库连接的地址,用户名以及密码

1 mysql.driverclass=com.mysql.jdbc.Driver
2 mysql.jdbcurl=jdbc:mysql://127.0.0.1:3306/shujuku_name?autoReconnect=true&useUnicode=true&characterEncoding=utf8
3 mysql.user=root
4 mysql.password=abc123

jdbc-context.xml:spring mvc的jdbc连接数据库的bean的配置

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans" 
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 7     xmlns:context="http://www.springframework.org/schema/context" 
 8     xmlns:cache="http://www.springframework.org/schema/cache"
 9     xsi:schemaLocation="   
10           http://www.springframework.org/schema/beans   
11           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd   
12           http://www.springframework.org/schema/tx   
13           http://www.springframework.org/schema/tx/spring-tx-3.1.xsd  
14           http://www.springframework.org/schema/context   
15           http://www.springframework.org/schema/context/spring-context-3.1.xsd   
16           http://www.springframework.org/schema/aop   
17           http://www.springframework.org/schema/aop/spring-aop-3.1.xsd" default-autowire="byName">
18            
19         <!-- 创建数据源   commons-dbcp.jar;     commons-pool.jar包-->
20      <context:property-placeholder location="classpath:database.properties"/>
21      <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
22         <property name="driverClassName" value="${mysql.driverclass}" />
23         <property name="url" value="${mysql.jdbcurl}" />
24         <property name="username" value="${mysql.user}" />
25         <property name="password" value="${mysql.password}" />
26      </bean>
27  
28      <bean id="simpleJdbcTemplate" class="org.springframework.jdbc.core.simple.SimpleJdbcTemplate">
29         <constructor-arg><ref bean="dataSource"/></constructor-arg>
30      </bean> 
31      
32      <!-- 看了spring源码,该 org.springframework.jdbc.core.JdbcTemplate类的继承类有dataSource属性,所以可以属性注入-->
33      <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
34          <property name="dataSource">
35              <ref bean="dataSource"/>
36          </property>
37      </bean>
38       
39 </beans>

springMvc3-servlet.xml:spring mvc的其他配置(非常重要)

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans" 
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" 
 4     xmlns:context="http://www.springframework.org/schema/context" 
 5     xmlns:mvc="http://www.springframework.org/schema/mvc" 
 6     xsi:schemaLocation="   
 7            http://www.springframework.org/schema/beans   
 8            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd   
 9            http://www.springframework.org/schema/context   
10            http://www.springframework.org/schema/context/spring-context-3.1.xsd  
11            http://www.springframework.org/schema/mvc   
12            http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
13      
14     <!-- 启动扫描所有的controller -->
15     <context:component-scan base-package="com.codingyun.core.action"/>
16      
17     <!--  主要作用于@Controller,激活该模式
18          
19         下面是一种简写形式,完全可以手动配置替代这种简写形式;
20          它会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean,
21            是spring MVC为@Controllers分发请求所必须的
22      -->
23 <!--     <mvc:annotation-driven/> -->
24     <mvc:annotation-driven>
25         <mvc:message-converters register-defaults="true">
26             <bean class="org.springframework.http.converter.StringHttpMessageConverter">
27                 <constructor-arg value="UTF-8" />
28             </bean>
29         </mvc:message-converters>
30     </mvc:annotation-driven>
31      
32    
33     <!-- 配置js,css等静态文件直接映射到对应的文件夹,不被DispatcherServlet处理 -->
34     <mvc:resources location="/WEB-INF/resources/**" mapping="/resources"/>
35     <mvc:resources mapping="/javascript/**" location="/static_resources/javascript/"/>  
36     <mvc:resources mapping="/styles/**" location="/static/css/"/>  
37     <mvc:resources mapping="/images/**" location="/static/images/"/> 
38      
39     <!-- 配置页面访问地址www.xxx.com/about返回的静态html文件 -->
40     <mvc:resources mapping="/about/**" location="/WEB-INF/html/"/>
41     <!-- 走servlet的默认配置,先走默认的web.xml配置的servlet,没有的话才找对应controller -->
42     <mvc:default-servlet-handler />
43      
44     <!-- jsp页面解析器,当Controller返回XXX字符串时,先通过拦截器,然后该类就会在jsp/目录下,查找XXX.jsp文件-->
45     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
46         <property name="prefix" value="/WEB-INF/jsp/"></property>
47         <property name="suffix" value=".jsp"></property>
48     </bean>
49      
50     <bean id="multipartResolver"
51         class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
52         <property name="defaultEncoding">
53             <value>UTF-8</value>
54         </property>
55         <property name="maxUploadSize">
56             <value>32505856</value><!-- 上传文件大小限制为31M,31*1024*1024 -->
57         </property>
58         <property name="maxInMemorySize">
59             <value>4096</value>
60         </property>
61     </bean>
62      
63 </beans>

log4j.properties:控制台打印日志的配置、输出日志文件的配置

 1 log4j.rootLogger=INFO,console,R
 2  
 3 log4j.appender.console=org.apache.log4j.ConsoleAppender
 4 log4j.appender.console.Target=System.out
 5 log4j.appender.console.layout=org.apache.log4j.PatternLayout
 6 log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%5p] - %c -%F(%L) -%m%n
 7 log4j.appender.console.threshold=INFO
 8  
 9 log4j.appender.R=org.apache.log4j.RollingFileAppender
10 log4j.appender.R.layout=org.apache.log4j.PatternLayout
11 log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%5p] - %c -%F(%L) -%m%n
12 log4j.appender.R.File=/alidata/zkyj/web/zkyj-web.log
13 log4j.appender.R.Append=true
14 log4j.appender.R.Threshold=INFO
15 log4j.appender.R.MaxFileSize=20MB
16 log4j.appender.LOGFILE.MaxBackupIndex=100
17 log4j.org.springframework.web=INFO

三、配置web.xml,以及新建jsp、css、js等目录

web.xml的配置:(如下)

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns="http://java.sun.com/xml/ns/javaee"
 4     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">
 5     <display-name>zkyj-web</display-name>
 6      
 7     <!-- web.xml 的加载顺序是:context-param -> listener -> filter -> servlet ,
 8     而同个类型之间的实际程序调用的时候的顺序是根据对应的 mapping 的顺序进行调用的 -->
 9      
10     <!-- spring上下文载入监听器,确保web服务启动时,spring已经完成初始化 -->
11     <listener>
12         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
13     </listener>
14      
15     <context-param>
16         <param-name>contextConfigLocation</param-name>
17         <param-value>classpath:jdbc-context.xml</param-value>
18     </context-param>  
19      
20     <filter>
21         <filter-name>encodingFilter</filter-name>
22         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
23         <init-param>
24             <param-name>encoding</param-name>
25             <param-value>UTF-8</param-value>
26         </init-param>
27         <init-param>
28             <param-name>ForceEncoding</param-name>
29             <param-value>true</param-value>
30         </init-param>
31     </filter>
32    
33     <filter-mapping>
34         <filter-name>encodingFilter</filter-name>
35         <url-pattern>/*</url-pattern>
36     </filter-mapping>
37  
38     <servlet>
39         <servlet-name>springMvc3</servlet-name>
40         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
41         <init-param>
42             <param-name>contextConfigLocation</param-name>
43             <param-value>classpath:springMvc3-servlet.xml</param-value>
44         </init-param>
45         <load-on-startup>1</load-on-startup>
46     </servlet>
47    
48     <!-- 会话超时配置(单位为分钟) -->
49     <session-config> 
50         <session-timeout>120</session-timeout> 
51     </session-config>
52    
53    
54     <servlet-mapping>     
55         <servlet-name>default</servlet-name>    
56         <url-pattern>*.jpg</url-pattern>       
57     </servlet-mapping>      
58     <servlet-mapping>         
59         <servlet-name>default</servlet-name>      
60         <url-pattern>*.js</url-pattern>      
61     </servlet-mapping>      
62     <servlet-mapping>          
63         <servlet-name>default</servlet-name>         
64         <url-pattern>*.css</url-pattern>        
65     </servlet-mapping>   
66     <servlet-mapping>
67         <servlet-name>springMvc3</servlet-name>
68         <url-pattern>/</url-pattern>
69     </servlet-mapping>            
70     <welcome-file-list>
71         <welcome-file>index.html</welcome-file>
72     </welcome-file-list>
73    
74     <!-- 通过错误码来配置error-page ,配置了当系统发生404错误时,跳转到错误处理页面NotFound.jsp。 -->
75     <error-page> 
76         <error-code>404</error-code> 
77         <location>/page404.html</location> 
78     </error-page> 
79     <!--  通过异常的类型配置error-page ,配置了当系统发生java.lang.NullException(即空指针异常)时,跳转到错误处理页面error.jsp  -->
80     <error-page> 
81         <exception-type>java.lang.NullPointerException</exception-type> 
82         <location>/WEB-INF/jsp/error.jsp</location> 
83     </error-page>
84    
85 </web-app>

接下来你就可以大显身手,随你想怎么弄,,,
