springboot如何访问windows本地和linux上的外部文件？
首先编写一个WebMvcConfiguration配置文件类
@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {

@Value("${jarPath}")     //file:/root/gspackage/
private String path;
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/**").addResourceLocations(path);
配置文件中新增静态映射，需要先把springboot默认的映射加上，用file来进行指定想要访问的静态目录

linux服务器上以"/"表示跟目录，windows可以用file: d: 来进行映射
配置方式参考如下:
spring:

static-path-pattern: /**

resources:

static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,classpath:/itstyle/, file:/
springsecurity的一些记录

@EnableWebSecurity

@Configuration

public class SercurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
UserDetailsServiceImpl userDetailsService;
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    super.configure(auth);
    //密码编码器
    BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
    InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
    User user = new User();
    user.setId(1);
    user.setName("xiaoming");
    user.setPassword("123456");
    user.setRole("USER");
    manager.createUser(user);
    //使用内存存储
    auth.inMemoryAuthentication()
            //设置密码编码器
            .passwordEncoder(passwordEncoder)
            //注册用户admin,密码为abc，并赋予USER和ADMIN的角色权限
            .withUser("admin")
            //可通过passwordEncoder.encode("abc")得到加密后的密钥
            .password("11111111111111")
            //赋予角色ROLE_USER和ROLE_ADMIN
            .roles("USER", "ADMIN")
            //连接方法and
            .and()
            //注册用户myuser，密码为123456，并赋予USER的角色权限
            .withUser("myuser")
            //可通过passwordEncoder.encode("123456")得到加密后的密钥
            .password("333333333333333333")
            //赋予角色ROLE_USER
            .roles("USER");
    //2种方式可以处理权限认证的过程
    auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
@Override
public void configure(WebSecurity web) throws Exception {
    super.configure(web);
    FilterSecurityInterceptor interceptor = new FilterSecurityInterceptor();
    //获取到拦截器，来处理一些拦截信息
    web.securityInterceptor(interceptor);
@Override
protected void configure(HttpSecurity http) throws Exception {
    super.configure(http);
    //需要spring security保护的断点
    String[] endpoints = {
            "auditevents", "beans", "conditions", "configprops", "env", "flyway", "httptrace",
            "loggers", "liquibase", "metrics", "mappings", "scheduledtasks", "sessions", "shutdown", "threaddump"
    //定义需要验证的端点
    http.requestMatcher(EndpointRequest.to(endpoints))
            //签名登录后
            .authorizeRequests().anyRequest()
            //要求登录用户拥有ADMIN角色
            .hasRole("ADMIN")
            .and()
            //请求关闭页面需要ROLE_ADMIN角色
            .antMatcher("close").authorizeRequests().anyRequest().hasRole("ADMIN")
            .and()
            //启动http基础验证
            .httpBasic();
    //处理对http请求的拦截认证
    http.authorizeRequests()
            .antMatchers("/test").permitAll()
            .antMatchers("/login").permitAll()
            .antMatchers("/look").hasRole("user")
            .antMatchers("/**").fullyAuthenticated()
            .and()
            .formLogin().loginPage("/login")
            .failureForwardUrl("/error")
            .successForwardUrl("/index");
