SpringBoot乱码

1.接受表单乱码

添加配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.StringHttpMessageConverter;

import java.nio.charset.Charset;

@Configuration
public class CharsetConfiguration {
    @Bean
    public HttpMessageConverter<String> responseBodyConverter() {
        StringHttpMessageConverter converter = new StringHttpMessageConverter(
                Charset.forName("UTF-8"));
        return converter;
    }
}

2.数据库乱码 我选择在URL中添加编码信息

注意我的数据库是UTF8mb4，哎神烦用这个编码，全UTF8多好

同样设置为UTF8亦可 如下配置

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/school?serverTimezone=UTC&useSSL=false&characterEncoding=UTF-8

 3.剩下的乱码我还没遇到 据说是

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8
