1.針對url傳參或form表單傳參

@InitBinder
public void initBinder(final WebDataBinder webdataBinder) {
    //去除首尾空格
    webdataBinder.registerCustomEditor(String.class, new PropertyEditorSupport() {
        @Override
        public void setAsText(String text) throws IllegalArgumentException {
            setValue(htmlUtils.htmlEscape(text, "UTF-8"));
        }
    });
}

2.針對Body的JSON格式傳參

1.自定義string 反序列化實現(xiàn)

public final class JsonStringDeserializer extends JsonDeserializer<String> {

    @Override
    public String deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
        String text = jsonParser.getText();
        return HtmlUtils.htmlEscape(text, "UTF-8");
    }
}

2.配置反序列化類

@Configuration
public class BaseMvcConfig implements WebMvcConfigurer {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        MAppingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.registerModule(getSimpleModule());
        jackson2HttpMessageConverter.setObjectMapper(objectMapper);
        converters.add(0, jackson2HttpMessageConverter);
    }

    private SimpleModule getSimpleModule() {
        SimpleModule simpleModule = new SimpleModule();
        simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
        simpleModule.addSerializer(Long.TYPE, ToStringSerializer.instance);
        //配置反序列化類
        simpleModule.addDeserializer(String.class, new JsonStringDeserializer());
        return simpleModule;
    }
}

順便說一下，序列化的設(shè)置一定要把Long轉(zhuǎn)成String。因為js對Long類型支持的精度不夠,導致后端使用的Long傳到前端丟失精度。這個是很大的坑。
