spring Security简单介绍：
Spring Security是一个功能强大且高度可定制的身份验证和访问控制框架，它是用于保护基于Spring的应用程序的实际标准。
Spring Security是一个框架，致力于为Java应用程序提供身份验证和授权。与所有Spring项目一样，Spring Security的真正强大之处在于可以轻松扩展以满足自定义要求。
简单实现
public class SecurityConfig extends WebSecurityConfigurerAdapter
{
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = httpSecurity
.authorizeRequests();
//不需要保护的资源路径允许访问
for (String url : ignoreUrlsConfig().getUrls()) {
registry.antMatchers(url).permitAll();
}
//允许跨域请求的OPTIONS请求
registry.antMatchers(HttpMethod.OPTIONS)
.permitAll();
// 任何请求需要身份认证
registry.and()
.authorizeRequests()
.anyRequest()
.authenticated()
// 关闭跨站请求防护及不使用session
.and()
.csrf()
.disable()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
// 自定义权限拒绝处理类
.and()
.exceptionHandling()
.accessDeniedHandler(restfulAccessDeniedHandler())
.authenticationEntryPoint(restAuthenticationEntryPoint())
// 自定义权限拦截器JWT过滤器
.and()
.addFilterBefore(jwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService())
.passwordEncoder(passwordEncoder());
}
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter() {
return new JwtAuthenticationTokenFilter();
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Bean
public RestfulAccessDeniedHandler restfulAccessDeniedHandler() {
return new RestfulAccessDeniedHandler();
}
@Bean
public RestAuthenticationEntryPoint restAuthenticationEntryPoint() {
return new RestAuthenticationEntryPoint();
}
@Bean
public IgnoreUrlsConfig ignoreUrlsConfig() {
return new IgnoreUrlsConfig();
}
@Bean
public JwtTokenUtil jwtTokenUtil() {
return new JwtTokenUtil();
}
}
