Java头

1)spring所有模块头信息

<?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:aop="http://www.springframework.org/schema/aop"
      xmlns:tx="http://www.springframework.org/schema/tx"
      xmlns:mvc="http://www.springframework.org/schema/mvc"
        
      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/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
    
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        
      ">
</beans>    

2)springMVC模板头信息 (一般放在)

<?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:mvc="http://www.springframework.org/schema/mvc"
        xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="

        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-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/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd

 ">
    
    
    
    <!-- Action处理类 -->      
    <bean name="/hello.action" class="cn.itcast.javaee.springmvc.hello.HelloAction"></bean>
    <!-- Action, 让spring-IOC容器去扫描带有@Controller的类 -->
    <context:component-scan base-package="com.ypd.springmvctest03.controller"/>

        
        
</beans>   

3) web.xml:

<?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"
         metadata-complete="true">
    <!--metadata-complete为true时,该web不会加载注解配置的web组件(如Servlet、Filter、Listener等)-->
    <!--配置Web应用的首页列表-->
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.htm</welcome-file>
    </welcome-file-list>

    <!-- 业务层和持久层的Spring配置文件,这些配置文件被父Spring容器所应用 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/DispatcherServlet-servlet.xml</param-value>
    </context-param>

    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 注册spring核心编码过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

4)xxx-servlet.xml 同 2)

5)jsp头

<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html>
<body>
    this the success jsp page.
</body>
</html>

注意pageEncoding要是UTF-8才能是好的,不然有可能乱码。

6)c3p0-config.xml的头

<?xml version="1.0" encoding="UTF-8"?>  
<c3p0-config>  
    <!-- 默认配置,只可以出现一次 -->  
    <default-config>  
        <!-- 连接超时设置30秒 -->   
        <property name="checkoutTimeout">3000</property>  
        <!-- 30秒检查一次connection的空闲 -->  
        <property name="idleConnectionTestPeriod">30</property>  
        <!--初始化的池大小 -->   
        <property name="initialPoolSize">2</property>  
        <!-- 最多的一个connection空闲时间 -->    
        <property name="maxIdleTime">30</property>  
        <!-- 最多可以有多少个连接connection -->  
        <property name="maxPoolSize">5</property>  
        <!-- 最少的池中有几个连接 -->  
        <property name="minPoolSize">2</property>  
        <!-- 批处理的语句 
         -->  
        <property name="maxStatements">50</property>  
        <!-- 每次增长几个连接 -->  
        <property name="acquireIncrement">3</property>  
        <property name="driverClass">com.mysql.jdbc.Driver</property>  
        <property name="jdbcUrl">  
            <![CDATA[jdbc:mysql://127.0.0.1:3306/bookstore?useUnicode=true&characterEncoding=UTF-8]]>  
        </property>  
        <property name="user">root</property>  
        <property name="password">root</property>  
    </default-config>   
</c3p0-config> 

7)xxx.hbm.xml:

<?xml version="1.0" encoding='UTF-8'?>  
<!DOCTYPE hibernate-mapping PUBLIC   
     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"   
     "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  
<hibernate-mapping >  
   <classname="类名" table="表名">  
      <id name="主键在java类中的字段名" column="对应表中字段" type="类型 ">  
          <generator class="主键生成策略"/>  
      </id>  
  
          ……   
    </class>  
</hibernate-mapping>   
  1. hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- 连接数据库的信息 -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/itheima1128elec?useUnicode=true&amp;characterEncoding=utf8</property>
        <property name="hibernate.connection.username">root</property>

        <!-- 添加映射 -->
        <mapping resource="com/itheima/elec/domain/ElecText.hbm.xml"/>
        <mapping resource="com/itheima/elec/domain/ElecCommonMsg.hbm.xml">

直接拷贝:

<!-- https://mvnrepository.com/artifact/commons-logging/commons-logging -->
<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.1.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/org.springframework.asm -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>org.springframework.asm</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-beans -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-core -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-expression -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-expression</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>



2.MVC的:

直接复制:

<!-- https://mvnrepository.com/artifact/org.springframework/org.springframework.web.servlet -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>org.springframework.web.servlet</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>

3.web的:

图片.png

直接复制:

<!-- https://mvnrepository.com/artifact/org.springframework/spring-web -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>

注意:如果这个不行就用下面的代替:

<dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-web</artifactId>
       <version>3.0.5.RELEASE</version>
</dependency>
