Spring-boot中增加filter，特别是自定义filter的步骤：

1.添加@ServletComponentScan

2.在@ServletComponentScan描的路径上增加被@WebFilter(filterName="myFilter",urlPatterns="/*")注解的类

@WebFilter(filterName="myFilter",urlPatterns="/*")
public class MyOpenSessionFilter implements Filter {
    
    private final OpenSessionInViewFilter filter;

    public MyOpenSessionFilter() {
        filter = new OpenSessionInViewFilter();
        filter.setSessionFactoryBeanName("sessionFactory_soc");
        
    }
    
    

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        filter.init(filterConfig);
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        filter.doFilter(request, response, chain);
    }

    @Override
    public void destroy() {
        filter.destroy();
    }
    
}

另外：@Order注解调整顺序
