## README

## 项目部署

1. 修改resources下配置
2. 执行resources下db中sql文件

## 自定义注解实现Token校验幂等性

 ```java
//1.自定义注解@ApiIdempotent
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface ApiIdempotent {
}

// 2.拦截器
public class ApiIdempotentInterceptor implements HandlerInterceptor {
}

// 3.处理业务逻辑
@Service
public class TokenServiceImpl implements TokenService {
}

// 4.拦截器注册
// 4.1本例子
@SpringBootApplication
@MapperScan("com.wangzaiplus.test.mapper")
public class TestApplication  extends WebMvcConfigurerAdapter {
//···
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 接口幂等性拦截器
        registry.addInterceptor(apiIdempotentInterceptor());
        super.addInterceptors(registry);
    }

    @Bean
    public ApiIdempotentInterceptor apiIdempotentInterceptor() {
        return new ApiIdempotentInterceptor();
    }
}
//4.2 标准添加
//—————————————————————————————————————————————————————————
@Configuration
public class WebAppConfigurer implements WebMvcConfigurer {


    /**
     * 注入自定义拦截器到该配置类中
     */
    @Autowired
    private MyInterceptor myInterceptor;

    /**
     * 解决跨域问题
     * @param registry
     */
    @Override
    public void addCorsMappings(CorsRegistry registry) {

        registry.addMapping("/**")
                .allowCredentials(true)
                .allowedHeaders("*")
                .allowedOrigins("*")
                .allowedMethods("*");

    }


    /**
     * 配置不需要拦截的请求
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {

        String[] patterns = new String[]{"/login","/**/*.html","/image/*","/","/static/**"};
        registry.addInterceptor(myInterceptor)
                .addPathPatterns("/**") // 拦截的访问路径，拦截所有
                .excludePathPatterns(patterns); // 排除的请求路径(不会被拦截)，排除静态资源路径

    }


    /**
     * 配置图片请求的映射
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

        registry.addResourceHandler("/image/**").addResourceLocations("D:\\userImages");

    }

}
