springboot三种通过代码达到配置的方式 @Configuration
@Configuration用编码实现配置转化
1，单纯的注入配置自己的类，后续类直接io使用（自己加入的配置文件）
ioc，注入
@Configuration
public class ValidatorConfig {
/**
* 报文数据的验证程序
* @return
*/
@Bean
public Validator validator(){
Validator validator = Validation.byProvider( HibernateValidator.class )
.configure()
.failFast( true )
.buildValidatorFactory()
.getValidator();
return validator;
}
@Bean
public PacketValidator packetValidator(){
return new PacketValidator();
}
}
di使用
@Autowired
private PacketValidator packetValidator;
2，覆盖默认的装配配置（覆盖方法） extends 。。。Adpater（复写系统自动装配的配置文件）
@Configuration
public class SettWebMvcConfiger extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
//registry.addResourceHandler("/js/");
//registry.addResourceHandler("/static/");
}
}
3,覆盖默认的配置（覆盖bean,覆盖方法），extends 。。。Adapter，并且注入（复写系统自动装配的配置文件）
@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CasProperties casProperties;
/** 定义认证用户信息获取来源，密码校验规则等 */
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
super.configure(auth);
auth.authenticationProvider(casAuthenticationProvider());
}
/** 定义安全策略 */
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()// 配置安全策略
.antMatchers("/","/hello","/static/**/*","/public/**/*","/js/**/*","/account/**/*").permitAll()//定义/请求不需要验证
.antMatchers("/*").permitAll()
// .antMatchers("/parj").permitAll()
// .antMatchers("/pacj").permitAll()
//.anyRequest().authenticated()// 其余的所有请求都需要验证
.and().logout().permitAll()// 定义logout不需要验证
.and().formLogin()
.and().csrf().ignoringAntMatchers("/*");
http.exceptionHandling().authenticationEntryPoint(casAuthenticationEntryPoint()).and().addFilter(casAuthenticationFilter()).addFilterBefore(casLogoutFilter(), LogoutFilter.class)
.addFilterBefore(singleSignOutFilter(), CasAuthenticationFilter.class);
}
/** 认证的入口 */
@Bean
public CasAuthenticationEntryPoint casAuthenticationEntryPoint() {
CasAuthenticationEntryPoint casAuthenticationEntryPoint = new CasAuthenticationEntryPoint();
casAuthenticationEntryPoint.setLoginUrl(casProperties.getCasServerLoginUrl());
casAuthenticationEntryPoint.setServiceProperties(serviceProperties());
return casAuthenticationEntryPoint;
}
/** 指定service相关信息 */
@Bean
public ServiceProperties serviceProperties() {
ServiceProperties serviceProperties = new ServiceProperties();
serviceProperties.setService(casProperties.getAppServerUrl() + casProperties.getAppLoginUrl());
serviceProperties.setAuthenticateAllArtifacts(true);
return serviceProperties;
}
/** CAS认证过滤器 */
@Bean
public CasAuthenticationFilter casAuthenticationFilter() throws Exception {
CasAuthenticationFilter casAuthenticationFilter = new CasAuthenticationFilter();
casAuthenticationFilter.setAuthenticationManager(authenticationManager());
casAuthenticationFilter.setFilterProcessesUrl(casProperties.getAppLoginUrl());
return casAuthenticationFilter;
}
/** cas认证Provider */
@Bean
public CasAuthenticationProvider casAuthenticationProvider() {
CasAuthenticationProvider casAuthenticationProvider = new CasAuthenticationProvider();
casAuthenticationProvider.setAuthenticationUserDetailsService(customUserDetailsService());
// casAuthenticationProvider.setUserDetailsService(customUserDetailsService());//这里只是接口类型，实现的接口不一样，都可以的。
casAuthenticationProvider.setServiceProperties(serviceProperties());
casAuthenticationProvider.setTicketValidator(cas20ServiceTicketValidator());
casAuthenticationProvider.setKey("casAuthenticationProviderKey");
return casAuthenticationProvider;
}
/*
* @Bean publicUserDetailsServicecustomUserDetailsService(){
* returnnewCustomUserDetailsService(); }
*/
/** 用户自定义的AuthenticationUserDetailsService */
@Bean
public AuthenticationUserDetailsService<CasAssertionAuthenticationToken> customUserDetailsService() {
return new CustomUserDetailsService();
}
@Bean
public TicketValidator cas20ServiceTicketValidator() {
return new Cas20ServiceTicketValidator(casProperties.getCasServerUrl());
}
/** 单点登出过滤器 */
@Bean
public SingleSignOutFilter singleSignOutFilter() {
SingleSignOutFilter singleSignOutFilter = new SingleSignOutFilter();
singleSignOutFilter.setCasServerUrlPrefix(casProperties.getCasServerUrl());
singleSignOutFilter.setIgnoreInitConfiguration(true);
return singleSignOutFilter;
}
/** 请求单点退出过滤器 */
@Bean
public LogoutFilter casLogoutFilter() {
LogoutFilter logoutFilter = new LogoutFilter(casProperties.getCasServerLogoutUrl(), new SecurityContextLogoutHandler());
logoutFilter.setFilterProcessesUrl(casProperties.getAppLogoutUrl());
return logoutFilter;
}
}
