诠注验证

注解验证
http://www.opensymphony.com/webwork/wikidocs/J2SE%205%20Support.html
http://www.opensymphony.com/webwork/wikidocs/Validation%20Annotation.html
WEBWORK中需要加入包xwork-tiger

一般有两种注解法

1.直接注在get方法上面，像这种

@RequiredStringValidator(message="Supply password")

public String getPassword() {
       
return password;
    }

2.注在方法上面，like

@Validations(
requiredStrings={
@RequiredStringValidator(fieldName="username",message="用户名不能为空!" key="i18n,國際化功能"),
@RequiredStringValidator(fieldName="telNum",message="电话号码不能为空!")
},
regexFields={@RegexFieldValidator(fieldName="telNum",expression="^(\\+86|0|1)\\d{10,11}$",
message="电话号码格式不正确！")}
)

}

public void setDown(File down) {
this.down = down;
}

public String getDownFileName() {
return downFileName;
}

public void setDownFileName(String downFileName) {
this.downFileName = downFileName;
}

public String getDownContentType() {
return downContentType;
}

public void setDownContentType(String downContentType) {
this.downContentType = downContentType;
}

public Page getPage() {
return page;
}

public void setPage(Page page) {
this.page = page;
}

public JSONObject getJsonObject() {
return jsonObject;
}

public void setJsonObject(JSONObject jsonObject) {
this.jsonObject = jsonObject;
}

public Timestamp getStart() {

}

this.start = start;
}

public Timestamp getEnd() {

}

public void setEnd(Timestamp end) {
this.end = end;
}

@Validations(requiredStrings = {
@RequiredStringValidator(fieldName = "downFileName", message = "请输入附件标题"),
@RequiredStringValidator(fieldName = "downFileName", message = "请输入附件") })
public String addDown() {
return SUCCESS;
}

@Validations(requiredStrings = {
@RequiredStringValidator(fieldName = "downFileName", message = "请1"),
@RequiredStringValidator(fieldName = "downFileName", message = "") })
public String deleteDown() {
return SUCCESS;
}
}



但无论是哪种注解，默认情况下都是对这个action的所有方法进行验证。

如上面的图，我虽然给deleteDown和addDown两个方法都写了对应的验证注解，但是结果是访问delete的时候，add的验证也起作用了。

在struts2中好解决
