SpringBoot设置字符编码方式

1.创建servlet

@WebServlet(urlPatterns = "/MyServlet")
public class MyServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.getWriter().println("汉字检测，english test");
        //统一浏览器编码格式，不同浏览器因为初始编码格式不通用，所以用户使用时统一编码格式
        resp.setContentType("text/html;character = utf-8");
        resp.getWriter().flush();
        resp.getWriter().close();
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }
}

2.创建配置类文件systemconfig

@Configuration
public class SystemConfig {
    @Bean
    public FilterRegistrationBean characterEncodingFilterRegistrationBean(){
        //创建字符编码过滤器
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        //强制使用指定的字符编码
        characterEncodingFilter.setForceEncoding(true);
        //设置字符编码
        characterEncodingFilter.setEncoding("utf-8");

        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        //设置字符编码过滤器
        filterRegistrationBean.setFilter(characterEncodingFilter);
        //设置字符编码过滤器路径
        filterRegistrationBean.addUrlPatterns("/*");

        return filterRegistrationBean;
    }
}

3.添加核心配置类内容

#关闭springboot的http字符编码设置支持，自己定义的编码规则才能生效
server.servlet.encoding.enabled=false

仅需要添加核心配置文件内容

#设置请求响应字符编码
server.servlet.encoding.enabled=true
server.servlet.encoding.force=true
server.servlet.encoding.charset=utf-8

1、是否启用spring boot字符编码配置

2、是否强制更改字符编码配置

3、要更改的字符编码配置规则
