grails XML to Object綁定

Question

是否有一個grails插件或庫可以將XML數據映射到Java類Object中？

我正在尋找一些將xml數據映射到Java類字段的groovy類。

--- UPDATE -----

以下的Grails服務類嘗試做這個映射，但它不工作。

會有人提示如何糾正下面的代碼，使其工作？

感謝

class DataBinderService { 

boolean transactional = false 
def grailsApplication 
private BeanWrapper wrapper = new BeanWrapperImpl() 

public List bindAllXmlData (Class targetClass, GPathResult source, List properties) { 
    if (targetClass == null || source == null || properties == null) return null 
    def resultList = [] 
    def className = WordUtils.uncapitalize(targetClass.simpleName) 
    source[className]?.each { 
     def boundObj = bindXmlData(targetClass, it, properties) 
     System.out.println(boundObj) 
     resultList.add(boundObj) 
    } 
    return resultList 
} 

public Object bindXmlData (Class targetClass, GPathResult source, List properties) { 
    if (targetClass == null || source == null || properties == null) return null 
    def targetObject = grailsApplication.classLoader.loadClass(targetClass.name).newInstance() 
    if (targetObject) { 
     return bindXmlData(targetObject, source, properties) 
    } else { 
     return null 
    } 
} 

public Object bindXmlData (Object target, GPathResult source, List properties) { 
    if (target == null || source == null || properties == null) return null 
    wrapper.registerCustomEditor (Date.class, new CustomDateBinder()) 
    wrapper.setWrappedInstance(target) 
    properties.each {String property -> 
     if (property.contains('.')) {//This indicates a domain class to bind e.g. experiment.id -> Experiment 
      def propertyName = property.tokenize('.') 
      def id = source[propertyName[0]]["@${propertyName[1]}"]?.toString() 
      if (id != null) { 
       def subdomainInstance = null 
       try {subdomainInstance = grailsApplication.classLoader.loadClass("edu.kit.iism.experimentcenter.${WordUtils.capitalize(propertyName[0])}").get(id)} catch (Exception ex) {} 
       if (subdomainInstance != null) wrapper.setPropertyValue(propertyName[0], subdomainInstance) 
      } 
     } else if (property.equals('id')) { //The id property is set as an attribute rather than text 
      def id = source['@id']?.toString() 
      if (id != null) wrapper.setPropertyValue(property, id) 
     } else { //regular attributes 
      def prop = source[property]?.toString() 
      if (prop != null) wrapper.setPropertyValue(property, prop) 
     } 
    } 
    return target 
} 

}
