本篇文章为大家展示了Spring security中怎么自定义成功和失败,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
重命名包名 case3 为 case4
重命名 Case3Application.java 为 Case4Application.java
在 config(HttpSecurity http) 方法中对 formLogin 选项进行配置。需要包含以下设置:
创建 SuccessHandler 实现 AuthenticationSuccessHandler 接口,并实现 onAuthenticationSuccess 方法,自定义返回内容;
创建 FailureHandler 实现 AuthenticationFailureHandler 接口,并实现 onAuthenticationFailure 方法,自定义返回内容;
在 formLogin 配置项上增加 successHandler 和 failureHandler 配置
相关代码如下:
package net.txt100.learn.springsecurity.base.case4.config;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationSuccessHandler;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public PasswordEncoder passwordEncoder() {
// 配置密码的保护策略,spring security 默认使用 bcrypt 加密算法。
// 此处只要显式声明 BCryptPasswordEncoder Bean 即可
return new BCryptPasswordEncoder();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
AuthenticationSuccessHandler successHandler = new AuthenticationSuccessHandler() {
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
response.setContentType("application/json;charset=UTF-8");
JSON.writeJSONString(response.getOutputStream(), authentication);
}
};
AuthenticationFailureHandler failureHandler = new AuthenticationFailureHandler() {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
response.setContentType("application/json;charset=UTF-8");
JSON.writeJSONString(response.getOutputStream(), exception);
}
};
http
.csrf().disable() // 关闭 CSRF 保护功能,否则不支持 Post 请求
.authorizeRequests() // 针对 HttpServletRequest 进行安全配置
.antMatchers("/login.html").permitAll() // login.html 页面无需登录即可访问
.anyRequest().authenticated() // 对所有 Request 均需安全认证
.and().formLogin()
.successHandler(successHandler)
.failureHandler(failureHandler)
.and().httpBasic(); // 定义如何验证用户,此项代表弹出浏览器认证窗口
}
}
