    #### 第三种方式（继承JsonSerializer）
    _自定义CustomDateSerializer类，在get属性方法上注入即可：_
    ```
    public class CustomDateSerializer extends JsonSerializer<Date> {
    @Override
    public void serialize(Date value, JsonGenerator gen, SerializerProvider arg2) throws
    IOException, JsonProcessingException {
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
    String formattedDate = formatter.format(value);
    gen.writeString(formattedDate);
    }
    }
    //date getter method
    @JsonSerialize(using = CustomDateSerializer.class)
    public Date getDate() {
    return date;
    }
    ```

    #### 第四种方式（页面js处理）

    var __dateConverter = function(param, fmt) {
    if (param) {
    const date = new Date(param);
    if (fmt == 'yyyy-mm') {

    #### 第一种方式（全局）
    _继承该类WebMvcConfigurerAdapter，注入如下bean：_
    ```
    @Bean
    public Converter<String, Date> stringToDateConvert() {
    return new Converter<String, Date>() {
    @Override
    public Date convert(String source) {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    Date date = null;
    try {
    date = sdf.parse(source);
    } catch (Exception e) {
    e.printStackTrace();
    }
    return date;
    }
    };
    }
    ```
    #### 第二种方式（特定某个controller）
    _直接在controller中加入如下代码：_
    ```
    @InitBinder
    public void initBinder(WebDataBinder binder){
    binder.registerCustomEditor(Date.class,
    new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true));
    }
    ```
