方法一：

import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.filter.CharacterEncodingFilter;
    
    import java.nio.charset.StandardCharsets;
    
    /**
     * spring boot 解决中文乱码
     */
    @Configuration
    public class CharacterEncodingFilterConfig {
        @Bean
        public FilterRegistrationBean filterRegistrationBean() {
            //用于注册过滤器
            FilterRegistrationBean frb = new FilterRegistrationBean();
            // 使用spring 提供的字符编码过滤器，不用自己写过滤器
            CharacterEncodingFilter cef = new CharacterEncodingFilter(StandardCharsets.UTF_8.toString(),true);
            frb.setFilter(cef);
            return frb;
        }
    }

方法二：

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 org.springframework.web.servlet.config.annotation.EnableWebMvc;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
    import java.nio.charset.StandardCharsets;
    import java.util.List;
    
    @Configuration
    @EnableWebMvc
    public class MvcConfig extends WebMvcConfigurationSupport {
    
        /**
         * 解决中文乱码的问题
         *
         */
        @Bean
        public HttpMessageConverter<String> responseBodyConverter() {
            return new StringHttpMessageConverter(StandardCharsets.UTF_8);
        }
    
        @Override
        public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
            converters.add(responseBodyConverter());
            super.configureMessageConverters(converters);
        }
    }

方法三：

#在application.properties编写如下四行
    
    spring.http.encoding.force=true #是否将编码强制到HTTP请求和响应上配置的字符集。默认为false
    spring.http.encoding.enabled=true #是否启用http编码支持。默认为false
    spring.http.encoding.charset=UTF-8 #HTTP请求和响应的字符集。如果没有明确设置,就将该字符集添加到Content-Type中
    server.tomcat.uri-encoding=UTF-8 #用于解码URI的字符编码。
