Question

我尝试使用@Validated注释来将有效的表单数据返回给控制器，但它无法调用我创建的自定义验证器。代码如下：

@PostMapping("/saveTransaction")
    public String saveTransaction(@ModelAttribute("transaction") 
@Validated Transactions transaction, BindingResult bindingResult) {

    if(bindingResult.hasErrors()) {
        System.out.println("Non formated form stuff.");
        return "transactions/transactionsForm";
    }

如果我手动调用Validator，则代码可以工作：

@PostMapping("/saveTransaction")
    public String saveTransaction(@ModelAttribute("transaction") Transactions transaction, BindingResult bindingResult) {
        validator.validate(transaction, bindingResult);
        if(bindingResult.hasErrors()) {
            System.out.println("Non formated form stuff.");
            return "transactions/transactionsForm";
        }

我正在使用以下代码自动连接我的类并初始化验证器。

    @Autowired
    private TransactionService transactionService;

    @Autowired
    @Qualifier("transactionValidator")
    private Validator validator;

    @InitBinder
    private void initBinder(WebDataBinder binder) {
        binder.setValidator(validator);
    }

I have the following code in Spring.xml file:

    <mvc:annotation-driven validator="transactionValidator" />

    <bean id="transactionValidator" class="org.lexusmanson.lexbudget.validator.TransactionValidator" />

为什么赢取注释会调用我的验证码？

Answer 1

你可以尝试@valid annotation而不是@validated希望它会有所帮助。

Answer 2

如下所述更改代码：绑定结果应在@Valid注释

之后

@PostMapping("/saveTransaction")
    public String saveTransaction(@Valid Transactions transaction, BindingResult bindingResult) {
        validator.validate(transaction, bindingResult);
        if(bindingResult.hasErrors()) {
            System.out.println("Non formated form stuff.");
            return "transactions/transactionsForm";
        }

Answer 3

1：如果尚未添加，则添加以下依赖项

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>

2：使用@Valid Annotation而不是@Validated annotation

3：在bean事务中使用一些验证约束，如@ NotEmpty，@ NotNull等

希望它适合你。

@Validated注释不起作用
