Question

I am using spring boot in my project and I run some encoding issue.

In the project, there is a controller(below) which accept request with a content type header ,\"appli

Answer 1

Adding the CharacterEncodingFilter bean can solve the problem ,seeing form https://github.com/spring-projects/spring-boot/issues/1182

@Bean
CharacterEncodingFilter characterEncodingFilter() {
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF-8");
    filter.setForceEncoding(true);
    return filter;
}

Answer 2

I had a similar problem and found that Spring Boot has "forceEncoding" enabled by default. This causes the request charset to be overridden and set to UTF-8 every time in their filter.

See Appendix A. Common application properties

The key part is:

Defaults to true when "force" has not been specified.

So setting either

spring.http.encoding.force=false

or

spring.http.encoding.force-request=false

Should solve your problem, as long as the request has the correct headers.
