当输入验证发生冲突时禁用JSF按钮

// 验证器类
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

public class InputValidator implements Validator {

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        // 进行输入验证的逻辑判断
        boolean validationFailed = false;
        // ...

        if (validationFailed) {
            // 验证失败，设置按钮禁用表达式的值为true
            component.getAttributes().put("disabled", true);
            throw new ValidatorException(new FacesMessage("输入验证失败"));
        } else {
            // 验证成功，设置按钮禁用表达式的值为false
            component.getAttributes().put("disabled", false);
        }
    }
}

<!-- JSF页面 -->
<h:form>
    <h:inputText value="#{bean.inputValue}" validator="#{inputValidator.validate}" />
    <h:commandButton value="提交" disabled="#{bean.buttonDisabled}" />
</h:form>
