通过template来把参数添加至对应的字符串中

1.  getTemplate()方法分别用来获取模板，以及配置好参数的模板

/** * 根据TransCode读取模板，模板中的参数被处理 * @param transCode * @param params * @return */public String getTemplate(String transCode, Map params) {Assert.hasLength(transCode, "TransCode不能为空!");Assert.notNull(params);Template template = this.getTemplate(transCode);StringWriter writer = new StringWriter();try {template.process(params, writer);} catch (TemplateException e) {log.error(e.getMessage());} catch (IOException e) {log.error(e.getMessage());}String rv = writer.toString();try{rv = xmlTrimByPattern(rv);}catch(Exception e){log.error(e.getMessage());}return rv;}/** * 根据TransCode读取模板，模板中的参数没有被处理 * @param transCode * @return */public Template getTemplate(String transCode) {Assert.hasLength(transCode, "TransCode不能为空!");Map cm = CgsManager.getInstance().getTemplateMap();if(cm.isEmpty()){System.out.println("缓存加载失败,请联系管理员");}String fileName = transCode + ".xml";String strloader = null;if(cm.containsKey(fileName)){strloader = cm.get(fileName).toString();}else{System.out.println("不存在模板!");return null;}Template template = null;Configuration cfg = new Configuration();try {cfg.setTemplateLoader(new StringTemplateLoader(strloader));template = cfg.getTemplate("");} catch (IOException e) {log.error(e.getMessage());}return template;}

 

 

2. StringTemplateLoader类

package cgs.util;import java.io.IOException;import java.io.Reader;import java.io.StringReader;import java.util.HashMap;import java.util.Map;import freemarker.cache.TemplateLoader;public class StringTemplateLoader implements TemplateLoader {private static final String DEFAULT_TEMPLATE_KEY = "_default_template_key";private Map templates = new HashMap();public StringTemplateLoader(String defaultTemplate) {if (defaultTemplate != null && !defaultTemplate.equals("")) {templates.put(DEFAULT_TEMPLATE_KEY, defaultTemplate);}}public void AddTemplate(String name, String template) {if (name == null || template == null || name.equals("")|| template.equals("")) {return;}if (!templates.containsKey(name)) {templates.put(name, template);}}public void closeTemplateSource(Object templateSource) throws IOException {}public Object findTemplateSource(String name) throws IOException {if (name == null || name.equals("")) {name = DEFAULT_TEMPLATE_KEY;}return templates.get(name);}public long getLastModified(Object templateSource) {return 0;}public Reader getReader(Object templateSource, String encoding)throws IOException {return new StringReader((String) templateSource);}}
