2.1 SpringSecurity配置

SpringSecurity主要配置类为WebSecurityConfig类。其中，主要用其实现类进行配置，代码如下：

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
    }
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    }
}
