FreeMarker的使用

引入的jar包：

1 import freemarker.core.Environment;
2 import freemarker.core.TemplateElement;
3 import freemarker.ext.beans.StringModel;
4 import freemarker.template.Configuration;
5 import freemarker.template.Template;
6 import freemarker.template.TemplateModelException;
7 import freemarker.template.TemplateSequenceModel;

简单的代码的例子：

 1 @Resource
 2     private FreeMarkerConfigurer freemarkerConfigurer;
 3     
 4     @Resource
 5     private ServletContext servletContext;
 6 
 7     public String getPraseHtmlFormTemplate(String templateString,Map<String, Object> paramMap, boolean readOnly,
 8             IInitCallback initCallback,boolean preview) {
 9         return praseHtmlFormTemplate(templateString, paramMap, readOnly, initCallback,preview);
10     }
11     
12     protected String praseHtmlFormTemplate(String templateString, 
13             Map<String, Object> paramMap, boolean readOnly,IInitCallback initCallback,boolean preview) {
14         Configuration cfg =freemarkerConfigurer.getConfiguration();
15         cfg.setCustomAttribute("initCallback", initCallback);
16         cfg.setCustomAttribute("readOnly", readOnly);
17         cfg.setCustomAttribute("preview", preview);
18         cfg.setTemplateLoader(new StringTemplateLoader(templateString)); 
19         Template template;
20         try {
21             template = cfg.getTemplate("");
22             StringWriter writer = new StringWriter();
23             Environment env = template.createProcessingEnvironment(paramMap, writer); 
24             env.setCustomAttribute("paramMap", paramMap);
25             env.process(); 
26             return writer.toString();
27         } catch (Exception e) {
28             logger.error("解析模板文件错误:" + e.getMessage());
29             e.printStackTrace();
30         }
31         return "";
32     }
