现有web系统替换成Spring Boot2框架 之7 拦截器 spring bootmaven拦截器addInterceptors

1. 自定义拦截器java类，继承HandlerInterceptorAdapter。例如LoginAnnotationInterceptor

 

2. 编写配置类，实现WebMvcConfigurer，重写addInterceptors方法，添加自定义的拦截器

例如：拦截URL 中的*.do *.action等

 

@Configuration

public class SystemWebMvcConfig implements WebMvcConfigurer{

 

@Autowired

private LoginAnnotationInterceptor loginAnnotationInterceptor;


@Override

    public void configurePathMatch(PathMatchConfigurer configurer) {

        configurer.setUseRegisteredSuffixPatternMatch(true);

    }


@Override

public void addInterceptors(InterceptorRegistry registry) {

List<String> excludeList = new ArrayList<String>(); registry.addInterceptor(loginAnnotationInterceptor).addPathPatterns("/**/**/**.do").excludePathPatterns(excludeList);

}

}

 

注：

registry.addInterceptor(loginAnnotationInterceptor).addPathPatterns("/**/**/**.do").excludePathPatterns(excludeList);

“/**/**/**.do”，每一个/**代表一层目录，只用一个/**.do只能拦截“loginAct.do”无法拦截“bss/user/user!goList.do”。所以要拦截所有的.do请求需要按照最深的目录配置
