2、修改配置文件

<?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:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
        <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
            <property name="templateLoaderPath" value="/WEB-INF/ftl/" />
            <property name="defaultEncoding" value="UTF-8" />
        </bean>
    </beans>

3、整合测试

@Controller
    public class HtmlGenController { 
    
        @Autowired
        private FreeMarkerConfigurer freeMarkerConfigurer;
    
        @RequestMapping("/genhtml")
        @ResponseBody
        public String genHtml()throws Exception {
            // 1、从spring容器中获得FreeMarkerConfigurer对象。
            // 2、从FreeMarkerConfigurer对象中获得Configuration对象。
            Configuration configuration = freeMarkerConfigurer.getConfiguration();
            // 3、使用Configuration对象获得Template对象。
            Template template = configuration.getTemplate("hello.ftl");
            // 4、创建数据集
            Map dataModel = new HashMap<>();
            dataModel.put("hello", "1000");
            // 5、创建输出文件的Writer对象。
            Writer out = new FileWriter(new File("D:/temp/term197/out/spring-freemarker.html"));
            // 6、调用模板对象的process方法，生成文件。
            template.process(dataModel, out);
            // 7、关闭流。
            out.close();
            return "OK";
        }
    }
