ftl文件转变成StringWriter

1.spring重配置

<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath">
<value>/WEB-INF/views/</value>
</property>
<property name="defaultEncoding" value="utf-8" />
<property name="freemarkerSettings">
<props>
<prop key="default_encoding">UTF-8</prop>
<prop key="output_encoding">UTF-8</prop>
<prop key="locale">zh_CN</prop>
<prop key="date_format">yyyy-MM-dd</prop>
<prop key="time_format">HH:mm:ss</prop>
<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
<prop key="classic_compatible">true</prop>
</props>
</property>
</bean>
<bean class="jyd.info.controller.FreemarkerUtils">
<property name="freeMarkerConfigurer" ref="freemarkerConfig" />
</bean>

2.java代码

package jyd.info.controller;

import java.io.FileWriter;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

 

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

import freemarker.template.Template;

public class FreemarkerUtils {
private static FreeMarkerConfigurer freeMarkerConfigurer;
public void setFreeMarkerConfigurer(FreeMarkerConfigurer freeMarkerConfigurer){
this.freeMarkerConfigurer=freeMarkerConfigurer;
}
public static void exportHtml(Map<String, Object> root,String outFile){
try {
Template template = freeMarkerConfigurer.getConfiguration().getTemplate(outFile+".ftl");
StringWriter stringWriter = new StringWriter();
template.process(root, stringWriter);
System.out.println(stringWriter);
} catch (Exception e) {
e.printStackTrace();
}
}
}
