```
public LabelTag()
```
- 方法详细资料
  - setFor
```
public void setFor(String forId)
```
    Set the value of the 'for' attribute.
    Defaults to the value of AbstractDataBoundFormElementTag.getPath(); may be a runtime expression.
  - getFor
```
@Nullable
protected String getFor()
```
    Get the value of the 'id' attribute.
    May be a runtime expression.
  - writeTagContent
```
protected int writeTagContent(TagWriter tagWriter)
                       throws JspException
```
    Writes the opening 'label' tag and forces a block tag so that body content is written correctly.
    指定者:
    writeTagContent 在类中 AbstractFormTag
    返回:
    Tag.EVAL_BODY_INCLUDE
    抛出:
    JspException
  - getName
```
@Nullable
protected String getName()
                  throws JspException
```
    Overrides #getName() to always return null, because the 'name' attribute is not supported by the 'label' tag.
    覆盖:
    getName 在类中 AbstractDataBoundFormElementTag
    返回:
    the value for the HTML 'name' attribute
    抛出:
    JspException
  - resolveFor
```
protected String resolveFor()
                     throws JspException
```
    Determine the 'for' attribute value for this tag, autogenerating one if none specified.
    抛出:
    JspException
    另请参阅:

```
public int doEndTag()
             throws JspException
```
