SSM整合(環境搭建)

SSM整合(環境搭建)

以一個web專案為例子。

需要的jar

1.先搭建一個Springmvc(先測試可以連線得上)

在resource資料夾下建立一個springmvc.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: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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
    
 
        
    <!-- 設定使用註解的掃描controller類所在的包 -->    
    <context:component-scan base-package="com.etc.controller" />    
          
        
    <!-- 定義跳轉的檔案的前後綴 ,檢視模式配置,預設在跳轉時新增字首字尾-->    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">    
        <!-- 這裡的配置我的理解是自動給後面action的方法return的字串加上字首和字尾,變成一個 可用的url地址 -->    
        <property name="prefix" value="/WEB-INF/jsp/" />    
        <property name="suffix" value=".jsp" />    
    </bean>    
        
   
<!-- 檔案上傳解析器 -->
	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" >
		<!-- 設定檔案上傳的大小  -->
		<property name="defaultEncoding" value="utf-8"></property>
		<property name="maxUploadSize" value="1048567"/>
    </bean>

    
</beans>    

2.在WebContent下建立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"    
    version="3.0">    
     
     
    <!-- post編碼過濾器 -->    
    <filter>    
        <filter-name>encodingFilter</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>encodingFilter</filter-name>    
        <url-pattern>/*</url-pattern>    
    </filter-mapping>    
        
    <!-- 配置一個springmvc的攔截器 -->    
    <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: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>    
        
</web-app>

到此mvc配置好了、保證測試能通過。(建立controller,測試攔截器)

2.整合Spring和mybatis

1.建立myabtis-config.xml(我們有要註冊資料來源,工廠和、獲取session(三種自己補充))

<?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
  
<configuration>
<!--放myabtis的配置  -->
 

</configuration>

把配置資訊搬到spring裡面

建立applicationcontent.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: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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">   
    <!-- 這樣框架就會自動幫我們判斷請求型別,請求靜態檔案時就不會去尋找handler,而是直接找檔案。
              是當我們同時使用註解開發時,就會把所有的請求都轉到default-servlet-handler進行處理,此時訪問就會報錯404
              解決方法就是在springmvc.xml中新增如下配置 -->
    <mvc:annotation-driven/>                   
    <mvc:default-servlet-handler/>                    
                        
    
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/smbms?useUnicode=true&amp;characterEncoding=utf8" />
        <property name="username" value="root" />
        <property name="password" value="747452" />
    </bean> 
    
    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="configLocation" value="classpath:Mybatis-Config.xml" />
        <property name="dataSource" ref="dataSource" />
    </bean>
    
     
    
    <context:component-scan base-package="com.etc">
    
    </context:component-scan> 
    
    
    
    <!-- 針對產生了通用型會批量生產 -->
    <!-- DAO介面所在包名,Spring會自動查詢其下的類 ,包下的類需要使用@MapperScan註解,否則容器注入會失敗,產生的是開頭小寫於xml同名的的bean -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.etc.dao.user" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
    
    
    
</beans>

測試整合無誤

回到web.xml新增整合配置

<?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"    
    version="3.0">    
     
        
    <!-- 整合SSM時這個配置會幫你開啟容器  -->    
    <context-param>    
         <param-name>contextConfigLocation</param-name>    
        <param-value>classpath:applicationContent.xml</param-value>    
    </context-param>    
    <listener>    
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    
    </listener>    
        
    <!-- post編碼過濾器 -->    
    <filter>    
        <filter-name>encodingFilter</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>encodingFilter</filter-name>    
        <url-pattern>/*</url-pattern>    
    </filter-mapping>    
        
    <!-- 配置一個springmvc的攔截器 -->    
    <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: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>    
        
</web-app>

現在可以開始業務了。

在此之前需要配置日誌:(直接懟進去即可)

### 設定Logger輸出級別和輸出目的地 ###
#日誌記錄器輸出級別:fatal > error > warn > info >debug#
log4j.rootLogger=debug,stdout,logfile

### 把日誌資訊輸出到控制檯 ###
#日誌資訊輸出到控制檯#
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
#資訊列印到System.err上 #
log4j.appender.stdout.Target=System.err
#指定日誌佈局型別#
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout

### 把日誌資訊輸出到檔案:etc.log ###
#日誌資訊寫到檔案中 #
log4j.appender.logfile=org.apache.log4j.FileAppender
#指定日誌輸出的檔名#
log4j.appender.logfile.File=./power_company.log
#指定轉換模式#
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
#指定日誌佈局型別#
log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} %l %F %p %m%n
