装入依赖
引入spring-sercurity
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
编写配置文件
package com.java1234.config;
import com.java1234.common.security.LoginFailedHandler;
import com.java1234.common.security.LoginSucessHandler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
/**
* spring security配置
*/
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private LoginSucessHandler loginSucessHandler;
@Autowired
private LoginFailedHandler loginFailedHandler;
private static final String URL_WHITELIST[] = {"/login", "/logout", "/user/captcha", "/password", "/image/**", "/test/**"};
@Override
protected void configure(HttpSecurity http) throws Exception {
// 开启跨域 和 csrf攻击 关闭
http
.cors()
.and()

}
@Override

}
}
登录成功逻辑实现
package com.java1234.common.security;
import com.alibaba.druid.support.json.JSONUtils;
import com.java1234.common.constant.MsgConstant;
import com.java1234.entity.R;
import com.java1234.utils.JwtUtils;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Component
public class LoginSuccessHandler implements AuthenticationSuccessHandler {
@Override
public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
httpServletResponse.setContentType("application/json;charset=utc-8");
ServletOutputStream outputStream = httpServletResponse.getOutputStream();
String username = "user";
String token = JwtUtils.genJwtToken(username);
outputStream.write(JSONUtils.toJSONString((R.ok(MsgConstant.LOGIN_SUCCESS).put("authorization",token))).getBytes());//将数据转换成json字符串写入到输出流中
outputStream.flush();//发送数据到前端
outputStream.close();
}
}
