freemarker加载模板文件的

java代码：

public String getContent(String name, HashMap<String, Object> paramMap) {

//home 文件路径 + name （模版文件名称)  paramMap包含(页面参过来的参数值)
String content = "";
try {
paramMap.put("name", name);
paramMap.put("templ", this);
paramMap.put("param", paramMap);
this.paramMap = paramMap;

Configuration configuration = new Configuration();
configuration.setDirectoryForTemplateLoading(ZDZServiceManager.getEnv().getHomeFile(home));
configuration.setObjectWrapper(new DefaultObjectWrapper());
configuration.setDefaultEncoding("UTF-8");

Template template = configuration.getTemplate(name);

StringWriter writer = new StringWriter();
template.process(paramMap, writer);//页面参数与模版文件交互
content = writer.toString();
} catch (Exception ex) {
log.error("Cannot get schema content {} !", name, ex);
}
return content;
}
