标签：springmvc freemarker easyui
最近项目一直在用SpringMVC+ Easyui +FreeMarker,最近比较有时间，重新复习一下，整个的搭建的过程，以及使用。
FreeMarker是模板引擎，是一种基于模板的、用来生成输出文本的通用工具,是基于Java的开发包和类库的。FreeMarker被设计用来生成HTML Web页面，特别是基于MVC（Model View Controller）模式的应用程序，FreeMarker与Web容器无关，即在Web运行时，它并不知道Servlet或HTTP，使用Servlet提供的数据动态地生成 HTML。
FreeMarker跟JSP相比，JSP运行时，需要在被执行的时候编译成Servlet, FreeMarker模板技术不存在编译，所以效率上FreeMarker会比较好，而且Freemarker内置了很多web编程中很常用的方法（日期转换、数字格式化等）方便开发人员操作。
Easyui是一种基于jQuery的用户界面插件集合，提供了大多数UI控件的使用，如：accordion，combobox，menu，dialog，tabs，validatebox，datagrid，window，tree等。
我们先看一下实现的列表，这样我们在整合时，就是接下来我们要分析的，这样思路会比较清晰，如图所示：
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<!-- 解决JSON中文乱码问题 -->
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/plain;charset=UTF-8</value>
<value>text/html;charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 该类只有org.springframework.web-3.1.2.RELEASE.jar及以上版本才有 使用该配置后，才可以使用JSON相关的一些注解-->
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/plain;charset=UTF-8</value>
<value>text/html;charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
<property name="objectMapper">
<!-- jackson-databind-2.2.2.jar -->
<bean class="com.fasterxml.jackson.databind.ObjectMapper">
<property name="dateFormat">
<bean class="java.text.SimpleDateFormat">
<constructor-arg value="yyyy-MM-dd HH:mm:ss" />
</bean>
</property>
</bean>
</property>
</bean>
</list>
</property>
<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 请求映射-->
<property name="webBindingInitializer">
<bean class="cn.social.card.util.DateBinding" />
</property>
</bean> 说明：
2）messageConverters是一个列表，列表中有StringHttpMessageConverter、MappingJackson2HttpMessageConverter等都指定了supportedMediaTypes所支持的类型，如果请求头Accept与某个messageConverter的supportedMediaTypes匹配，那么将使用此messageConverter向响应体输出内容。
（1）MappingJackson2HttpMessageConverter：使用 Jackson 的ObjectMapper 读取/编写 JSON 数据。它转换媒体类型为 application/json 的数据。该类只有org.springframework.web-3.1.2.RELEASE.jar及以上版本才有使用该配置后，才可以使用JSON相关的一些注解，并可以配置日期的格式需要引入jackson-databind-2.2.2.jar：如图所示：
2. webBindingInitializer属性配置
1）webBindingInitializer是全局的属性编辑器，我们配置了日期格式化，有可以配置电话等格式。我们自定义全局的属性编辑器时，需要实现了WebBindingInitializer接口中的initBinder方法，代码如下：
public class DateBinding implements WebBindingInitializer {
/**
* 表单数据（全部是字符串）通过WebDataBinder进行绑定到命令对象，内部通过PropertyEditor实现
*/
public void initBinder(WebDataBinder binder, WebRequest request) {
//使用spring自带的CustomDateEditor
//注册自定义的属性编辑器(日期)
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
}
日期格式化全局实现好了，我们把这个类AnnotationMethodHandlerAdapter属性配置对应的，就OK了
2）也可以定义为局部的属性编辑器，只在对应的controller类里有效的
@InitBinder
public void initBinder(WebDataBinder binder)
<!-- 设置freeMarker的配置文件路径 --> <bean id="freemarkerConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="location" value="classpath:freemarker.properties" /> </bean> <bean id="xmlEscape" class="freemarker.template.utility.XmlEscape" /> <!-- freeMarker的模板配置 --> <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <!--视图解析器会在/WEB-INF/template/路径下查找--> <property name="templateLoaderPath"> <value>/WEB-INF/template/</value> </property> <property name="freemarkerVariables"> <map> <entry key="xml_escape" value-ref="xmlEscape" /> </map> </property> <property name="freemarkerSettings" ref="freemarkerConfiguration" /> </bean> <!-- 配置freeMarker视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" /> <!--查找对应下所有以ftl结尾的文件--> <property name="viewNames" value="*.ftl" /> <property name="contentType" value="text/html; charset=utf-8" /> <property name="cache" value="true" /> <property name="prefix" value="" /> <property name="suffix" value="" /> <property name="order" value="1"></property> <property name="requestContextAttribute" value="rc" /> </bean>
