在Spring Security Rest中定制登录响应,可以通过以下步骤实现:
下面是一个示例代码:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private JwtUtils jwtUtils;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/api/public/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin().disable()
.httpBasic().disable()
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint())
.and()
.addFilterBefore(authenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);
}
@Bean
public AuthenticationEntryPoint authenticationEntryPoint() {
return (request, response, authException) -> {
response.setContentType("application/json;charset=UTF-8");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
response.getWriter().write("{\"error\": \"Unauthorized\"}");
};
}
@Bean
public AuthenticationTokenFilter authenticationTokenFilter() {
return new AuthenticationTokenFilter(jwtUtils);
}
@Bean
public AuthenticationSuccessHandler authenticationSuccessHandler() {
return (request, response, authentication) -> {
response.setContentType("application/json;charset=UTF-8");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().write("{\"token\": \"" + jwtUtils.generateToken(authentication) + "\"}");
};
}
@Bean
public AuthenticationFailureHandler authenticationFailureHandler() {
return (request, response, exception) -> {
response.setContentType("application/json;charset=UTF-8");
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
response.getWriter().write("{\"error\": \"" + exception.getMessage() + "\"}");
};
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// 配置用户认证逻辑
}
}
在上述代码中,我们通过重写 configure 方法配置了自定义的认证成功处理器和认证失败处理器,并将其添加到 Spring Security 的配置中。在认证成功处理器中,我们生成了一个 JWT,并将其作为响应返回给客户端。在认证失败处理器中,我们将认证失败的错误信息返回给客户端。
这样,当用户进行登录操作时,Spring Security Rest 将会使用我们自定义的处理器来处理登录成功和失败的情况,从而实现定制化的登录响应。
