javaBean使用注解方式转成xml中，给元素添加CDATA的方法

该注解使用的是jdk自带的rt.jar包下的

1、javaBean注解如下：

@XmlAccessorType(XmlAccessType.FIELD)  
@XmlRootElement(name="process")
public class Process extends BaseAttribute{
	@XmlAttribute(name="isExecutable")  
	String isExecutable;

	@XmlElement(name = "sequenceFlow") 
	List sequenceFlows;//线条集合
	
	public Process() {  
        super();  
    }  
  
    public Process(String id,String name,String documentation,String isExecutable,
    		List sequenceFlows) {  
    		super(id, name, documentation);  
        this.sequenceFlows = sequenceFlows;
        
    }  
    
	public String getIsExecutable() {
		return isExecutable;
	}

	public void setIsExecutable(String isExecutable) {
		this.isExecutable = isExecutable;
	}
	
	public List getSequenceFlows() {
		return sequenceFlows;
	}
	public void setSequenceFlows(List sequenceFlows) {
		this.sequenceFlows = sequenceFlows;
	}
}

@XmlAccessorType(XmlAccessType.FIELD)  
public class SequenceFlow extends BaseAttribute{
	
	@XmlAttribute(name="sourceRef")  
	String sourceRef;//源端
	
	@XmlAttribute(name="targetRef")  
	String targetRef;//目标端
	
	@XmlElement(name = "conditionExpression")  
	ConditionExpression conditionExpression;

	public SequenceFlow() {
		super();
	}

	public SequenceFlow(String id, String name,String documentation,String sourceRef,
			String targetRef,ConditionExpression conditionExpression) {
		super(id,name,documentation);
		this.sourceRef = sourceRef;
		this.targetRef = targetRef;
		this.conditionExpression = conditionExpression;
	}
	
	public String getSourceRef() {
		return sourceRef;
	}
	
	public void setSourceRef(String sourceRef) {
		this.sourceRef = sourceRef;
	}
	
	
	public String getTargetRef() {
		return targetRef;
	}
	public void setTargetRef(String targetRef) {
		this.targetRef = targetRef;
	}

	
	public ConditionExpression getConditionExpression() {
		return conditionExpression;
	}

	public void setConditionExpression(ConditionExpression conditionExpression) {
		this.conditionExpression = conditionExpression;
	}
}

@XmlAccessorType(XmlAccessType.FIELD)
public class ConditionExpression {
	
	@XmlAttribute(name="xsi:type")  
	String type;

	@XmlElement(name="conditionValue")  
	String conditionValue;
	
	public ConditionExpression(){
    }
    public ConditionExpression(String type,String conditionValue) {
        this.type = type;
        this.conditionValue = conditionValue;
    }
	
	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}
	public String getConditionValue() {
		return conditionValue;
	}
	public void setConditionValue(String conditionValue) {
		this.conditionValue = conditionValue;
	}
}

@XmlAccessorType(XmlAccessType.FIELD)  
public class BaseAttribute {
	@XmlAttribute(name="id")  
	public String id;//节点id
	@XmlAttribute(name="name")  
	public String name;//节点名称
	@XmlElement(name="documentation")  
	public String documentation;//描述信息
	
	public BaseAttribute(){
    }
    public BaseAttribute(String id,String name,String documentation) {
    	this.id = id;
    	this.name = name;
        this.documentation = documentation;
    }

	public String getId() {
		return id;
	}
	
	public void setId(String id) {
		this.id = id;
	}
	
	public String getName() {
		return name;
	}
	
	public void setName(String name) {
		this.name = name;
	}
	
	public String getDocumentation() {
		return documentation;
	}

	public void setDocumentation(String documentation) {
		this.documentation = documentation;
	}
}

2、生成xml的方法，这里注意将所有需要添加的元素都加到setCDataElements数组内，如下代码所示：

@SuppressWarnings("restriction")
public class BeanToXml2 {
    
    /**
     * java对象转换为xml文件
     * @param xmlPath  xml文件路径
     * @param load    java对象.Class
     * @return    xml文件的String
     * @throws JAXBException    
     */
    @SuppressWarnings("restriction")
	public static String beanToXml(Object obj,Class load) throws Exception{
        JAXBContext context = JAXBContext.newInstance(load);
        
        OutputFormat of = new OutputFormat(); 
        of.setCDataElements( 
        		new String[] { "^conditionValue"});
        
        of.setPreserveSpace(true); 
        of.setIndenting(true);
        ByteArrayOutputStream op = new ByteArrayOutputStream(); 
        XMLSerializer serializer = new XMLSerializer(op, of); 
        SAXResult result = new SAXResult(serializer.asContentHandler()); 
       
        Marshaller mar = context.createMarshaller(); 
        mar.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); 
        mar.marshal(obj, result); 
        return op.toString("UTF-8");
    }
    
    /**
    * @Title: getProcess
    * @Description: TODO(流程定义部分)
    * @return
    * @return Process (这里用一句话描述返回结果说明)
    */ 
    public Process getProcess(){
    	Process process = new Process();//2
    	process.setId("processId");
    	process.setName("名称");
    	process.setIsExecutable("true");
    	process.setSequenceFlows(getSequenceFlows());
    	return process;
    }
    
    public List getSequenceFlows(){
    	List sequenceFlows = new ArrayList();//线条集合  3.5
    	
    	ConditionExpression conditionExpression1 = new ConditionExpression("tFormalExpression","${pass}");
    	ConditionExpression conditionExpression2 = new ConditionExpression("tFormalExpression","${!pass}");
    	
    	SequenceFlow sequenceFlow1 = new SequenceFlow("flow10","同意",null,
    			"sourceId1","target1",conditionExpression1);
    	
    	SequenceFlow sequenceFlow2 = new SequenceFlow("flow11","退回",null,
    			"sourceId2","target2",conditionExpression2);

    	sequenceFlows.add(sequenceFlow1);
    	sequenceFlows.add(sequenceFlow2);
    	return sequenceFlows;
    }

    public static void main(String[] args) throws Exception {

    	BeanToXml2 beanToXml = new BeanToXml2();
    	
    	String str =  BeanToXml2.beanToXml(beanToXml.getProcess(), Process.class);
    	System.out.println(str);
        //写入到xml文件中
        String xmlPath = "D:/testConfig.bpmn";
        BufferedWriter bfw = new BufferedWriter(new FileWriter(new File(xmlPath)));
        bfw.write(str);
        bfw.close();
    }
}

3、最终生成的xml如下所示：
