| <h1 id="201-datedate-time">2.0.1 新特性介绍： date和date-time</h1> |
| <p>OpenAPI 针对时间定义了两种类型 <a href="https://swagger.io/docs/specification/data-models/data-types/#string">date 和 date-time</a>。 |
| JavaChassis 在2.0.1之前的版本只支持使用 date-time，而且必须要求使用 <code>java.util.Date</code> 作为运行时类型， |
| 2.0.1 版本扩充了 date 和 date-time 的实现，开发者可以使用更加灵活的方式使用这两种类型。</p> |
| <h2 id="date">使用 date</h2> |
| <p>可以在 query, path, body 等参数中使用 date 类型。 date 类型对应的 Java 类型为 <code>java.time.LocalDate</code>。 |
| 使用 Spring MVC， 分别采用如下方式定义接口：</p> |
| <pre><code class="language-java">@GetMapping(path = "/getLocalDate") |
| public LocalDate getLocalDate(@RequestParam("date") LocalDate date) { |
| return date; |
| } |
| |
| @GetMapping(path = "/getLocalDate/{date}") |
| public LocalDate getLocalDatePath(@PathParam("date") LocalDate date) { |
| return date; |
| } |
| |
| @PostMapping(path = "/postLocalDate") |
| public LocalDate postLocalDate(@RequestBody LocalDate date) { |
| return date; |
| } |
| </code></pre> |
| <p>其中 <code>getLocalDatePath</code> 接口定义生成的 swagger 描述如下：</p> |
| <pre><code class="language-yaml">/getLocalDate/{date}: |
| get: |
| operationId: "getLocalDatePath" |
| parameters: |
| - name: "date" |
| in: "path" |
| required: true |
| type: "string" |
| format: "date" |
| responses: |
| "200": |
| description: "response of 200" |
| schema: |
| type: "string" |
| format: "date" |
| </code></pre> |
| <p>可以看出，date 在网络上是通过 String 进行编码进行传输的， 格式是标准的格式， 比如 <code>2020-02-20</code>。</p> |
| <h2 id="date-time">使用 date-time</h2> |
| <p>可以在 query, path, body 等参数中使用 date-time 类型。 date 类型对应的 Java 类型为 <code>java.time.LocalDateTime</code>， |
| 或者 <code>java.util.Date</code> 。 |
| 使用 Spring MVC， 分别采用如下方式定义接口：</p> |
| <pre><code class="language-java">@GetMapping(path = "/getDate") |
| public Date getDate(@RequestParam("date") Date date) { |
| return date; |
| } |
| |
| @GetMapping(path = "/getDatePath/{date}") |
| public Date getDatePath(@PathParam("date") Date date) { |
| return date; |
| } |
| |
| @PostMapping(path = "/postDate") |
| public Date postDate(@RequestBody Date date) { |
| return date; |
| } |
| |
| @GetMapping(path = "/getLocalDateTime") |
| public LocalDateTime getLocalDateTime(@RequestParam("date") LocalDateTime date) { |
| return date; |
| } |
| |
| @GetMapping(path = "/getLocalDateTime/{date}") |
| public LocalDateTime getLocalDateTimePath(@PathParam("date") LocalDateTime date) { |
| return date; |
| } |
| |
| @PostMapping(path = "/postLocalDateTime") |
| public LocalDateTime postLocalDateTime(@RequestBody LocalDateTime date) { |
| return date; |
| } |
| </code></pre> |
| <p>其中 <code>getLocalDateTimePath</code> 接口定义生成的 swagger 描述如下：</p> |
| <pre><code class="language-yaml">/getLocalDateTime/{date}: |
| get: |
| operationId: "getLocalDateTimePath" |
| parameters: |
| - name: "date" |
| in: "path" |
| required: true |
| type: "string" |
| format: "date-time" |
| responses: |
| "200": |
| description: "response of 200" |
| schema: |
| type: "string" |
| format: "date-time" |
| </code></pre> |
| <p>可以看出，date-time 在网络上是通过 String 进行编码进行传输的， 格式是标准的格式， 比如 <code>2017-07-21T17:32:28Z</code>。 |
| 由于 date-time 的标准格式包含特殊字符，在作为 query 或者 path 参数的时候， 需要做好 URL 编解码， |
| 网络上传递的实际内容为 <code>2017-07-21T17%3A32%3A28Z</code>， 比如： <code>http://localhost:8082/dateTime/getLocalDateTime?date=2017-07-21T17%3A32%3A28Z</code>, |
| 作为 body 参数， 内容不会编解码， 是引号包含起来的 String 类型， 比如 <code>"2017-07-21T17:32:28Z"</code>。</p> |
