spring 注解 xml配置 事务 aop面向切面 的知识点与理解

记录项目的spring mvc 的配置文件，spring 整合shiro和mybatis的配置xml文件   （）

1.springMvc的配置xml如下（spring-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" xmlns:aop="http://www.springframework.org/schema/aop"
       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 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
    <!-- 静态资源访问处理  -->
    <mvc:resources mapping="/js/**" location="/js/"/>
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/datas/**" location="/datas/"/>

    <!--开启AOP-->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
    <!-- 自动扫描该包 -->
    <context:component-scan base-package="com.gviiii.controller"/>
    <!-- 默认的注解映射的支持 -->
    <mvc:annotation-driven/>
    <!--解析返回JSON -->
    <!--  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> -->
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter"/>
            </list>
        </property>
    </bean>
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>

    <!-- 配置文件上传 -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!--默认编码-->
        <property name="defaultEncoding" value="utf-8" />
        <!--文件大小最大值-->
        <property name="maxUploadSize" value="10485760000" />
        <!--内存中的最大值-->
        <property name="maxInMemorySize" value="40960" />
    </bean>

    <!-- freemarker config -->
    <bean id="freemarkerConfiguration"
          class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:freemarker.properties"/>
    </bean>

    <!-- 配置freeMarker的模板路径 ,html路径在这里设置，视图解析里面配置无效-->
    <bean id="freemarkerConfig"
          class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="freemarkerSettings" ref="freemarkerConfiguration"/>
        <property name="templateLoaderPath" value="/views/"/>
    </bean>

    <!-- freemarker视图解析器 -->
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="cache" value="true"/>
        <property name="suffix" value=".html"/>
        <!--只是这里后缀改成.html -->

        <property name="viewClass" value="com.gviiii.expand.BaseFreeMarkerView"/>
        <property name="exposeSpringMacroHelpers" value="true"/>
        <property name="exposeRequestAttributes" value="true"/>
        <property name="exposeSessionAttributes" value="true"/>
        <property name="requestContextAttribute" value="request"/>
        <property name="contentType" value="text/html;charset=UTF-8"/>
    </bean>
</beans>

因为项目的表现层是 html 没有使用jsp 所以一部分页面是采用的freemarker来做后台与前端界面的交互，freemarker 整合中的BaseFreeMarkerView 类代码如下(BaseFreeMarkerView.java)：

package com.gviiii.expand;

import org.springframework.web.servlet.view.freemarker.FreeMarkerView;

import javax.servlet.http.HttpServletRequest;
import java.util.Map;

/**
 * @version V1.0.0
 * @classname BaseFreeMarkerView
 * @description description
 */
public class BaseFreeMarkerView extends FreeMarkerView {
    private static final String CONTEXT_PATH = "basePath";
    private static final String WEB_PATH = "webPath";

    @Override
    protected void exposeHelpers(Map<String, Object> model, HttpServletRequest request) throws Exception {
        String scheme = request.getScheme();
        String serverName = request.getServerName();
        int port = request.getServerPort();
        String path = request.getContextPath();
        String basePath = scheme + "://" + serverName + ":" + port + path;
        model.put(CONTEXT_PATH, basePath);
        model.put(WEB_PATH, path);
        super.exposeHelpers(model, request);
    }
}

这里freemarker的配置如下（freemarker.properties）

classic_compatible=true
##如果变量为null,转化为空字符串，比如做比较的时候按照空字符串做比较
whitespace_stripping=true
##去掉多余的空格，非常有用
##模板更新事件，设置为1秒，正式环境设置为3600秒
template_update_delay=1
##模板更新时间，这里配置是1秒更新一次，正式环境，模板不会改变，可以降这个值很大，提高效率
