要实现配置单个HttpSecurity
,可以通过在配置类中创建多个protected
的方法,并使用@Order
注解来指定它们的顺序来实现。每个protected
方法都会配置一个单独的HttpSecurity
对象。 下面是实现的步骤:
- 创建一个配置类,并添加
@EnableWebSecurity
注解。 - 在配置类中创建多个被
@Order
注解标记的protected
方法,每个方法都返回一个HttpSecurity
对象,例如:configure(HttpSecurity http)
,configureSecond(HttpSecurity http)
。 - 在头部添加
@Configuration
注解并将这些方法都声明为@Bean
注解。 - 配置每个
HttpSecurity
对象。这可能涉及到添加认证、授权规则、登录页、注销等配置。
下面是一个Spring Security
配置类示例:
@Configuration
@EnableWebSecurity
public class SecurityConfig {
@Configuration
@Order(1)
public static class WebSecurityConfigurerOne extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/api/**")
.authorizeRequests()
.antMatchers("/api/**").hasRole("ADMIN")
.and()
.httpBasic();
}
}
@Configuration
@Order(2)
public static class WebSecurityConfigurerTwo extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.antMatchers("/admin/**").hasRole("ADMIN")
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.defaultSuccessUrl("/home")
.permitAll()
.and()
.logout().permitAll();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user").password("password").roles("USER")
.and()
.withUser("admin").password("password").roles("USER", "ADMIN");
}
}
}
在这个例子中,我们创建了两个WebSecurityConfigurer类,定义了两个不同的HttpSecurity对象。具体的过程如下:
步骤1: 加上@EnableWebSecurity注解,使应用启用Spring Security功能。
@EnableWebSecurity
@Configuration
public class SecurityConfig {
// ...
}
步骤2: 创建一个WebSecurityConfigurer类,一个类代表一个单独的HttpSecurity。
@Configuration
@Order(1)
public static class WebSecurityConfigurerOne extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/api/**")
.authorizeRequests()
.antMatchers("/api/**").hasRole("ADMIN")
.and()
.httpBasic();
}
}
@Configuration
@Order(2)
public static class WebSecurityConfigurerTwo extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.antMatchers("/admin/**").hasRole("ADMIN")
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.defaultSuccessUrl("/home")
.permitAll()
.and()
.logout().permitAll();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user").password("password").roles("USER")
.and()
.withUser("admin").password("password").roles("USER", "ADMIN");
}
}
步骤3: 添加@Configuration和@Bean注解。
@Configuration
@EnableWebSecurity
public class SecurityConfig {
@Configuration
@Order(1)
public static class WebSecurityConfigurerOne extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/api/**")
.authorizeRequests()
.antMatchers("/api/**").hasRole("ADMIN")
.and()
.httpBasic();
}
}
@Configuration
@Order(2)
public static class WebSecurityConfigurerTwo extends WebSecurityConfigurerAdapter {
//...
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public AuthenticationManager customAuthenticationManager() throws Exception {
return authenticationManager();
}
}
下面是第二个示例,它展示了如何配置多个WebSecurityConfigurer方法来保护不同的url模式。
@Configuration
@EnableWebSecurity
public class MultipleEntryPointsSecurityConfig {
private static final String USER_ROLE = "USER";
private static final String ADMIN_ROLE = "ADMIN";
public MultipleEntryPointsSecurityConfig() {
super();
}
// configure the default security instance which will handle any request not mapped by the other instances
@Configuration
public static class DefaultSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider authProvider;
public DefaultSecurityConfig() {
super();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/public/**").permitAll()
.anyRequest().authenticated()
.and().exceptionHandling().accessDeniedPage("/login?error=true");
http.formLogin()
.loginPage("/login")
.failureUrl("/login?error=true")
.defaultSuccessUrl("/secure/home")
.and().logout().logoutSuccessUrl("/login?logout=true");
}
@Bean(name="authenticationManager")
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}
// configure the security instance accessible through the /secure/** URLs
@Configuration
@Order(1)
public static class SecureEntryPoint extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider authProvider;
public SecureEntryPoint() {
super();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/secure/**")
.authorizeRequests()
.antMatchers("/secure/trade/**").hasAnyRole(USER_ROLE, ADMIN_ROLE)
.antMatchers("/secure/admin/**").hasRole(ADMIN_ROLE)
.and().exceptionHandling().accessDeniedPage("/login?error=true");
http.formLogin()
.loginPage("/login")
.failureUrl("/login?error=true")
.defaultSuccessUrl("/secure/home")
.and().logout().logoutSuccessUrl("/login?logout=true");
}
}
// configure the security instance accessible through the /internal/** URLs
@Configuration
@Order(2)
public static class InternalEntryPoint extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider authProvider;
public InternalEntryPoint() {
super();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/internal/**")
.authorizeRequests()
.antMatchers("/internal/**").hasRole(ADMIN_ROLE)
.and().exceptionHandling().accessDeniedPage("/login?error=true");
http.formLogin()
.loginPage("/login")
.failureUrl("/login?error=true")
.defaultSuccessUrl("/internal/home")
.and().logout().logoutSuccessUrl("/login?logout=true");
}
}
}
这个示例中有3个WebSecurityConfigurer类,DefaultSecurityConfig,SecureEntryPoint和InternalEntryPoint,它们被@Order
注解标记,用来控制它们的优先级。
- DefaultSecurityConfig 方法配置了默认的安全实例,处理那些没有被其他实例配置的请求。 Login页设置为 /login,如果登录失败,会重定向到 /login?error=true,如果登录成功,会重定向到 /secure/home,访问被拒绝时,会返回 /login?error=true。
- SecureEntryPoint 此方法配置的安全实例可以通过 /secure/ 访问。它提供了对 /secure/trade/ 和 /secure/admin/** 的保护,并指定了不同的角色要求。 Login页设置为 /login,如果登录失败,会重定向到 /login?error=true,如果成功,则会重定向到 /secure/home。如果访问被拒绝,则会返回 /login?error=true。
- InternalEntryPoint 此方法配置的安全实例可以通过 /internal/ 访问。 它提供了对 /internal/** 的保护,并要求管理员角色。 Login页设置为 /login,如果登录失败,则重定向到/login?error=true,如果成功,则重定向到 /internal/home。 访问被拒绝时,返回 /login?error=true。
通过这个示例,我们可以看到SpringSecurity如何通过配置多个WebSecurityConfigurer类来保护不同的url模式。
