对 requestparam 的 spring 验证不起作用

Question

我正在尝试使用 @Min(1) 注释在 controller 中验证我的参数。 当我在单元测试中测试它时，它是 200。我不确定我做错了什么。 这是我的代码：

Controller：

@GetMapping(produces = "application/json")
    public Response search(@RequestParam(name = "firstname", required = false) String firstName,
        @RequestParam(name = "lastname", required = false) String lastName, @RequestParam("ibid") @Min(1) long ibId,
        @RequestParam(name = "workstationids", required = false) List<Long> workstationIds,
        @RequestParam("timerange") int timeRange,
        @RequestParam(name = "receivingstatus", required = false) String receivingStatus,
        @RequestParam(name = "displaystart", required = false) Integer displayStart,
        @RequestParam(name = "displaylength", required = false) Integer displayLength,
        @RequestParam("timezone") @NotBlank String timeZone) {
        ...
        ...

测试：

@Test
    public void searchWithInvalidParams() throws Exception {
        mockMvc.perform(get(BASE_URL)
            .param(COLUMN_IB_ID, INVALID_IB_ID_VALUE) //invalid ib id is "-1"
            .param(COLUMN_TIME_RANGE, TIME_RANGE_VALUE)
            .param(COLUMN_TIME_ZONE, TIME_ZONE)
            .andExpect(status().isBadRequest());
    }

我期望它返回 400，但结果是 200。

更新：所以我在 controller 中添加了@Validated 并添加了对 pom 的依赖，但它仍然不起作用（仍然是 200）

我的pom：

Answer 1

您已正确完成以下 2 个步骤：

1. 将 hibernate 验证器包含到 pom.xml
2. 为 controller 添加了 @Validated 注释

还需要两个步骤。 除了上述之外，你能做到这两个吗：

3. 向 pom.xml 添加一个条目（不确定为什么需要 javax.el）

    <dependency> <groupId>org.glassfish </groupId> <artifactId>javax.el </artifactId> <version>3.0.1-b11 </version> </dependency>

4. 将以下内容添加到您的 Java 配置 class

    @Bean public MethodValidationPostProcessor methodValidationPostProcessor() { return new MethodValidationPostProcessor(); }

（参考 - https://www.baeldung.com/spring-validate-requestparam-pathvariable ）

Answer 2

从 Boot 2.3 开始， @PathVariable @RequestParam所需的步骤是：

1. 添加依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

2. 将@Validated添加到 controller class
