spring.http.encoding.charset=UTF-8 # Charset of HTTP requests and responses. Added to the "Content-Type" header if not set explicitly.

spring.http.encoding.enabled=true # Enable http encoding support.

spring.http.encoding.force=true # Force the encoding to the configured charset on HTTP requests and responses.

public FilterRegistrationBean filterRegistrationBean() {

FilterRegistrationBean registrationBean = new FilterRegistrationBean();

CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();

characterEncodingFilter.setEncoding("UTF-8");

registrationBean.setFilter(characterEncodingFilter);

return registrationBean;
