springboot如何訪問windows本地和linux上的外部文件？
首先編寫一個WebMvcConfiguration配置文件類
@Configuration
public class WebMvcConfiguration implements WebMvcConfigurer {

@Value("${jarPath}")     //file:/root/gspackage/
private String path;

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/**").addResourceLocations(path);
}

}

配置文件中新增靜態(tài)映射，需要先把springboot默認(rèn)的映射加上，用file來進行指定想要訪問的靜態(tài)目錄
linux服務(wù)器上以"/"表示跟目錄，windows可以用file: d: 來進行映射

配置方式參考如下:

spring:
mvc:
static-path-pattern: /**
resources:
static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,classpath:/itstyle/, file:/

springsecurity的一些記錄
@EnableWebSecurity
@Configuration
public class SercurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
UserDetailsServiceImpl userDetailsService;

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    super.configure(auth);
    //密碼編碼器
    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);
    //使用內(nèi)存存儲
    auth.inMemoryAuthentication()
            //設(shè)置密碼編碼器
            .passwordEncoder(passwordEncoder)
            //注冊用戶admin,密碼為abc，并賦予USER和ADMIN的角色權(quán)限
            .withUser("admin")
            //可通過passwordEncoder.encode("abc")得到加密后的密鑰
            .password("11111111111111")
            //賦予角色ROLE_USER和ROLE_ADMIN
            .roles("USER", "ADMIN")
            //連接方法and
            .and()
            //注冊用戶myuser，密碼為123456，并賦予USER的角色權(quán)限
            .withUser("myuser")
            //可通過passwordEncoder.encode("123456")得到加密后的密鑰
            .password("333333333333333333")
            //賦予角色ROLE_USER
            .roles("USER");

    //2種方式可以處理權(quán)限認(rèn)證的過程
    auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}


@Override
public void configure(WebSecurity web) throws Exception {
    super.configure(web);
    FilterSecurityInterceptor interceptor = new FilterSecurityInterceptor();
    //獲取到攔截器，來處理一些攔截信息
    web.securityInterceptor(interceptor);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    super.configure(http);
    //需要spring security保護的斷點
    String[] endpoints = {
            "auditevents", "beans", "conditions", "configprops", "env", "flyway", "httptrace",
            "loggers", "liquibase", "metrics", "mappings", "scheduledtasks", "sessions", "shutdown", "threaddump"
    };
    //定義需要驗證的端點
    http.requestMatcher(EndpointRequest.to(endpoints))
            //簽名登錄后
            .authorizeRequests().anyRequest()
            //要求登錄用戶擁有ADMIN角色
            .hasRole("ADMIN")
            .and()
            //請求關(guān)閉頁面需要ROLE_ADMIN角色
            .antMatcher("close").authorizeRequests().anyRequest().hasRole("ADMIN")
            .and()
            //啟動http基礎(chǔ)驗證
            .httpBasic();

    //處理對http請求的攔截認(rèn)證
    http.authorizeRequests()
            .antMatchers("/test").permitAll()
            .antMatchers("/login").permitAll()
            .antMatchers("/look").hasRole("user")
            .antMatchers("/**").fullyAuthenticated()
            .and()
            .formLogin().loginPage("/login")
            .failureForwardUrl("/error")
            .successForwardUrl("/index");
