关于自定义标签的问题

[cristian_s]

我写了一个自定义标签的处理类，继承的是BodyTagSupport类，而且我是在doStartTag()方法里重新写input。但是我定义的标签是带标签体的，我不知道怎么把标签体的内容付给自定义标签的属性value？求高人指教

public class ButtonAuthorityTag extends BodyTagSupport {

	private static final long serialVersionUID = 1L;

	private final String DEFAULT_TYPE = "button";
	
	private final String DEFAULT_CLASS = "btn btn-primary";
	
	/**
     * Creates TagWriter
     * @return Created TagWriter
     */
    TagWriter createTagWriter() {
        TagWriter tagWriter = new TagWriter(this.pageContext);
        return tagWriter;
    }
    
    @Override
	public int doStartTag() throws JspException {
				
		if(StringUtil.isBlank(this.type)){
			type = this.DEFAULT_TYPE;
		}
		
		if(StringUtil.isBlank(this.cssClass)){
			cssClass = this.DEFAULT_CLASS;
		}
		
		TagWriter tagWriter = createTagWriter();
		//这里有个校验，成功返回true
		if (validate()) {
			tagWriter.startTag("input");
        	tagWriter.writeAttribute("type", type);
        	tagWriter.writeAttribute("id", id);
        	tagWriter.writeAttribute("name", name);
        	if (value.contains("spring:message")) {
        		MessageSource ms = (MessageSource) AppCtxUtil.getCtx().getBean("messageSource");
        		//截取code值
        		String key = value.replace(" ", "");
        		key = key.substring(key.indexOf("code=")+6);
        		key=key.substring(0,key.indexOf("/>")-1);
        		Locale lang = (Locale)session.getAttribute(SessionForm.LOCAL);
        		tagWriter.writeAttribute("value", ms.getMessage(key, null, lang));
			} else {
				tagWriter.writeAttribute("value", value);
			}
			tagWriter.writeAttribute("onclick", onclick);
        	tagWriter.writeAttribute("class", cssClass);
        	if ("true".equals(this.disabled)|| "disabled".equals(this.disabled)) {
				tagWriter.writeAttribute("disabled", disabled);
			}
			tagWriter.endTag();
        	return EVAL_BODY_INCLUDE;
			//return SKIP_BODY;
		}
		return SKIP_BODY;
	}	
	
    @Override
	public int doAfterBody() throws JspException {
		return SKIP_BODY;
	}
	
    @Override
	public int doEndTag() throws JspException {
		BodyContent bodyContent = super.getBodyContent();
		String body = bodyContent.getString();
		this.value = body;
		return EVAL_PAGE;
	}
	
    @Override
	public void doInitBody() throws JspException {
		
	}
    
    @Override
    public void setBodyContent(BodyContent bodyContent) {
    	this.bodyContent = bodyContent;
    }
    
	private String value = "";
	
	private String type = "";
	
	private String id = "";
	
	private String name = "";
	
	private String cssClass = "";
	
	private String onclick = "";
	
	private String disabled = "";
	

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}

	public String getType() {
		return type;
	}

	public void setType(String type) {
		this.type = type;
	}

	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 getCssClass() {
		return cssClass;
	}

	public void setCssClass(String cssClass) {
		this.cssClass = cssClass;
	}

	public String getOnclick() {
		return onclick;
	}

	public void setOnclick(String onclick) {
		this.onclick = onclick;
	}

	public String getDisabled() {
		return disabled;
	}

	public void setDisabled(String disabled) {
		this.disabled = disabled;
	}

JSP页面上的我的标签是这样<ts:buttonAuth type="button" onclick="search()" ><spring:message code='button.lable.Add'/></ts:buttonAuth> 我的疑惑是我想把标签体的内容也就是<spring:message code='button.lable.Add'/>赋值给value属性，但是我不知道怎么去获取标签体内的值。我用BodyContent bodyContent = super.getBodyContent();可是bodyContent是null，不知道为什么。
