structs 校验有错误
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator Config 1.0//EN"
"http://www.opensymphony.com/xwork/xwork-validator-config-1.0.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>username 不能为空</message>
</field-validator>
</field>
<field name="password">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>password不能为空</message>
</field-validator>
</field>
</validators>
为什么在每行代码下边都有黄色的波浪线啊？还有在<validators>标签有提示：The content of element type "validators" must match "(validator)+".
[解决办法]
头部换成
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.3//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.3.dtd">
