空检查@Null       验证对象是否为null@NotNull    验证对象是否不为null, 无法查检长度为0的字符串@NotBlank 检查约束字符串是不是Null还有被Trim的长度是否大于0,只对字符串,且会去掉前后空格.@NotEmpty 检查约束元素是否为NULL或者是EMPTY.Booelan检查@AssertTrue     验证 Boolean 对象是否为 true  @AssertFalse    验证 Boolean 对象是否为 false  长度检查@Size(min=, max=) 验证对象（Array,Collection,Map,String）长度是否在给定的范围之内  @Length(min=, max=) Validates that the annotated string is between min and max included.日期检查@Past           验证 Date 和 Calendar 对象是否在当前时间之前  @Future     验证 Date 和 Calendar 对象是否在当前时间之后  @Pattern    验证 String 对象是否符合正则表达式的规则数值检查，建议使用在Stirng,Integer类型，不建议使用在int类型上，因为表单值为“”时无法转换为int，但可以转换为Stirng为"",Integer为null@Min            验证 Number 和 String 对象是否大等于指定的值  @Max            验证 Number 和 String 对象是否小等于指定的值  @DecimalMax 被标注的值必须不大于约束中指定的最大值. 这个约束的参数是一个通过BigDecimal定义的最大值的字符串表示.小数存在精度@DecimalMin 被标注的值必须不小于约束中指定的最小值. 这个约束的参数是一个通过BigDecimal定义的最小值的字符串表示.小数存在精度@Digits     验证 Number 和 String 的构成是否合法  @Digits(integer=,fraction=) 验证字符串是否是符合指定格式的数字，interger指定整数精度，fraction指定小数精度。@Range(min=, max=) Checks whether the annotated value lies between (inclusive) the specified minimum and maximum.@Range(min=10000,max=50000,message="range.bean.wage")
private BigDecimal wage;@Valid 递归的对关联对象进行校验, 如果关联对象是个集合或者数组,那么对其中的元素进行递归校验,如果是一个map,则对其中的值部分进行校验.(是否进行递归验证)@CreditCardNumber信用卡验证@Email  验证是否是邮件地址，如果为null,不进行验证，算通过验证。@ScriptAssert(lang= ,script=, alias=)@URL(protocol=,host=, port=,regexp=, flags=)
