在MySQL数据库中创建springsecurity数据库
(id、username、password都是根据User.java映射过来的)
在application.properties中编写配置文件
#datasource
spring.datasource.url=jdbc:mysql:///springsecurity?serverTimezone=UTC&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.dricer-class-name=com.mysql.jdbc.Driver #jpa
#打印出数据库语句
spring.jpa.show-sql=true
#更新数据库表
spring.jpa.hibernate.ddl-auto=update
创建domain实体层User.java和repository存储层接口UserRepository.java
书写用户User.java实体

User.java
完善UserRepository.java接口，实现查找用户姓名方法
@Query(value = "select * from user where username = ?1",nativeQuery = true)
User findUserByUsername(String username);
在UserService.java中实现查找用户Service
@Autowired
private PasswordEncoder passwordEncoder; @Autowired
private UserRepository userRepository; //spring security默认处理登陆(username为输入的username)
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// TODO Auto-generated method stub
//System.out.println(username);
User user = userRepository.findUserByUsername(username);
//用户名，密码，权限
//User实现UserDetails接口
return new User(username,passwordEncoder.encode(user.getPassword()),AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
}
测试时发现，当用户输入错误的用户名和密码时，控制台会报空指针异常，前台为给出“坏的凭证”给用户提示信息。
原因：springsecurity会拦截一切其它的请求。只有当用户输入正确的用户名和密码，springsecurity才会释放用户正常的请求。
package com.Gary.GaryRESTful.config; import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder; //Web应用安全适配器
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter{ //告诉SpringSecurity密码用什么加密的
@Bean
public PasswordEncoder passwordEncoder()
{
return new BCryptPasswordEncoder();
} //表单验证(身份认证)
protected void configure(HttpSecurity http) throws Exception{
http.formLogin()
.and()
//请求授权
.authorizeRequests()
//所有请求都被拦截，跳转到(/login请求中)
.anyRequest()
//都需要我们身份认证
.authenticated();
} }
SecurityConfig.java
package com.Gary.GaryRESTful.repository; import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository; import com.Gary.GaryRESTful.domain.User; public interface UserRepository extends CrudRepository<User,Long>{ @Query(value = "select * from user where username = ?1",nativeQuery = true)
User findUserByUsername(String username); }
UserRepository.java
package com.Gary.GaryRESTful.service; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
//import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component; import com.Gary.GaryRESTful.domain.User;
import com.Gary.GaryRESTful.repository.UserRepository; //用SprinSecurity默认的登陆系统
//UserService要实现UserDetailsService接口
@Component
public class UserService implements UserDetailsService{ @Autowired
private PasswordEncoder passwordEncoder; @Autowired
private UserRepository userRepository; //spring security默认处理登陆(username为输入的username)
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// TODO Auto-generated method stub
//System.out.println(username);
User user = userRepository.findUserByUsername(username);
//用户名，密码，权限
//User实现UserDetails接口
return new User(username,passwordEncoder.encode(user.getPassword()),AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
} }
UserService.java
所以我们可以在UserDetails.java中进行修改，添加判断，如果在数据库中未查询到用户时返回null
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// TODO Auto-generated method stub
//System.out.println(username);
User user = userRepository.findUserByUsername(username);
//用户名，密码，权限
if(user == null)
{
throw new UsernameNotFoundException(username);
}
//User实现UserDetails接口
return new User(username,passwordEncoder.encode(user.getPassword()),AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
}
package com.Gary.GaryRESTful.service; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
//import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component; import com.Gary.GaryRESTful.domain.User;
import com.Gary.GaryRESTful.repository.UserRepository; //用SprinSecurity默认的登陆系统
//UserService要实现UserDetailsService接口
@Component
public class UserService implements UserDetailsService{ @Autowired
private PasswordEncoder passwordEncoder; @Autowired
private UserRepository userRepository; //spring security默认处理登陆(username为输入的username)
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// TODO Auto-generated method stub
//System.out.println(username);
User user = userRepository.findUserByUsername(username);
//用户名，密码，权限
if(user == null)
{
throw new UsernameNotFoundException(username);
}
//User实现UserDetails接口
return new User(username,passwordEncoder.encode(user.getPassword()),AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
} }
UserService.java
拓展：根据SpringSecurity提供的User方法
//给SpringSecurity用的构造方法
public User(String username,String password,
Collection<? extends GrantedAuthority> authorities) {
this(username,password,true,true,true,true,authorities);
}
可以在UserService.java中提供的UserDetails返回值中添加4个boolean值
return new User(user.getUsername(),passwordEncoder.encode(user.getPassword()),true,true,true,true,AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
这四个boolean值代表着
//用户是否没有失效
@Transient
private boolean accountNonExpried;
//用户是否冻结
@Transient
private boolean accountNonLocked;
//证明是否过期
@Transient
private boolean credentialsNonExpired;
//判断是否删除
@Transient
private boolean enabled;
如果return返回值中四个参数都为true，springscurity不会去进行拦截验证，
当其中一个参数为false时，springsecurity就会对用户进行拦截验证~
