Now, we want to check if the incoming Java object meets our requirements. As you are using Spring Boot web, Jackson dependency is implicit and we do not have to define explicitly. There are three ways to add your filter, Annotate your filter with one of the Spring stereotypes such as @Component; Register a @Bean with Filter type in Spring @Configuration; Register a @Bean with FilterRegistrationBean type in Spring @Configuration; Either #1 or #2 will do if you want your filter applies to all requests without customization, use #3 otherwise. You can even write a separate class and annotate with Spring Boot uses jackson by default to serialize, deserialize json data.. By default, Jackson serializes Date objects as timestamps. If you need a log level other than INFO, you can set it, as described in Log Levels.The application version is determined using the implementation version from the main application classs package. @ControllerAdvice @ControllerAdvice is a specialization of the @Component annotation which allows to handle exceptions across the whole application in one global handling component. For LocalDateTime, LocalDate objects, jackson doesnt do anything special, it just treats them as basic Java objects. If you're using curl on windows, try escaping the json like -d "{"name":"value"}" or even -d "{"""name""":"value"""}" On the other hand you can ommit the content-type header in which case whetewer is sent will be converted to your String argument On the other hand, Request Param just obtain the string I have two questions: How to map a list of JSON objects using Spring RestTemplate.
