Freemarker整合spring

添加依赖

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>

创建整合spring的配置文件

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

Freemarker整合spring

整合spring代码

@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";
    }
}
