三、创建映射对象
package cn.com.panji.common.resourcemanager.bean.web; import java.util.ArrayList; import java.util.List; import lombok.Data; /** Web资源文件方法集合 * * @author */ @Data public class WebTemplateMethods { private List<WebTemplateMethod> methods = new ArrayList<>(); public List<WebTemplateMethod> getMethods() { return methods; } public void setMethods(List<WebTemplateMethod> methods) { this.methods = methods; } public void addWebTemplateMethod(WebTemplateMethod method) { methods.add(method); } }
package cn.com.panji.common.resourcemanager.bean.web; import java.util.Arrays; import java.util.List; import cn.com.panji.common.util.StringUtils; import lombok.Data; /** Web资源文件方法实体 * * @author */ @Data public class WebTemplateMethod { private String name; private String discribe; private String id; private String comment; private String jimport; private String jbean; private String body; public String getBody() { // body.replace("<", "<"); // body.replace(">", ">"); return body; } public void setBody(String body) { this.body = body; } public String getDiscribe() { return discribe; } public void setDiscribe(String discribe) { this.discribe = discribe; } public String getComment() { return comment; } public void setComment(String comment) { this.comment = comment; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getJimport() { return jimport; } public List<String> getJimportList() { jimport = StringUtils.removeAllBlank(jimport); return Arrays.asList(jimport.split(";")); } public void setJimport(String jimport) { this.jimport = jimport; } public String getJbean() { return jbean; } public List<String> getJbeanList() { jbean = StringUtils.trim(jbean); return Arrays.asList(jbean.split(";")); } public void setJbean(String jbean) { this.jbean = jbean; } public String getId() { return id; } public void setId(String id) { this.id = id; } }
四、Digester解析配置与应用
package cn.com.panji.common.resourcemanager.api.impl; import java.io.IOException; import java.util.ArrayList; import java.util.Arrays; import java.util.HashMap; import java.util.List; import java.util.Map; import org.apache.commons.digester.Digester; import org.xml.sax.SAXException; import cn.com.panji.common.resourcemanager.ResourceEnum; import cn.com.panji.common.resourcemanager.api.TemplateXMLReader; import cn.com.panji.common.resourcemanager.bean.web.WebTemplateMethod; import cn.com.panji.common.resourcemanager.bean.web.WebTemplateMethods; public class WebTemplateXMLReader extends TemplateXMLReader { static final String WEB_TEMPLEATE_XML_PATH = "resourceTemplates/" + ResourceEnum.XML_TEMPLATE_WEB.getResourceTemplatePath() + ".xml"; private WebTemplateMethods methods = null; private WebTemplateXMLReader() { configDigester(); parse(); } @Override public void configDigester() { this.digester = new Digester(); this.digester.setValidating(false); // 配置映射 this.digester.addObjectCreate("webTemplate-methods", WebTemplateMethods.class); this.digester.addObjectCreate("webTemplate-methods/method", WebTemplateMethod.class); this.digester.addBeanPropertySetter("webTemplate-methods/method/name", "name"); this.digester.addBeanPropertySetter("webTemplate-methods/method/id", "id"); this.digester.addBeanPropertySetter("webTemplate-methods/method/discribe", "discribe"); this.digester.addBeanPropertySetter("webTemplate-methods/method/jimport", "jimport"); this.digester.addBeanPropertySetter("webTemplate-methods/method/jbean", "jbean"); this.digester.addBeanPropertySetter("webTemplate-methods/method/comment", "comment"); this.digester.addBeanPropertySetter("webTemplate-methods/method/body", "body"); this.digester.addSetNext("webTemplate-methods/method", "addWebTemplateMethod"); } @Override public void parse() { try { methods = (WebTemplateMethods) this.digester .parse(this.getClass().getClassLoader().getResourceAsStream(WEB_TEMPLEATE_XML_PATH)); } catch (IOException | SAXException e) { e.printStackTrace(); } } @Override public WebTemplateMethod findResource(String id) { for (WebTemplateMethod m : methods.getMethods()) { if (id.equals(m.getId())) { return m; } } return null; } @Override public Object findResourceMap(String[] ids) { Map<String, WebTemplateMethod> map = new HashMap<>(); List<String> idList = Arrays.asList(ids); for (WebTemplateMethod m : methods.getMethods()) { if (idList.contains(m.getId())) { map.put(m.getId(), m); } } return map; } @Override public Object findResourceList(String[] ids) { List<WebTemplateMethod> list = new ArrayList<WebTemplateMethod>(); List<String> idList = Arrays.asList(ids); for (WebTemplateMethod m : methods.getMethods()) { if (idList.contains(m.getId())) { list.add(m); } } return list; } public static TemplateXMLReader getInstance() { return new WebTemplateXMLReader(); } }
WebTemplateMethod web = (WebTemplateMethod) TemplateReaderFactory.getTemplateXMLReaderInstance(ResourceEnum.XML_TEMPLATE_WEB).findResource("updateMethod");
五、解释及注意事项
1.XML结构应与映射对象层次结构相同，解析时，可解析到最末端元素，关于List数据，使用事件驱动器进行反射，当扫描到元素时，调动相应的Add方法。
2.Digester使用反射Setter方式进行属性注入，需要保证存在有效的Setter方法。
3.项目中可用该方式实现更加清晰的项目参数配置文件以及解析。
