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;

}
