SpringSecurity的官方文檔及其簡單，他的示例配置就是在xml文件中把用戶名和密碼寫固定了，然而在實際工作中是不可能的，參考了下網(wǎng)上的教程發(fā)現(xiàn)良莠不齊，特此寫下記錄學習過程
首先pom導入jar包：
pom.xml

        
            org.glassfish.web

            1.2.2

            1.2
        
        
            javax

            junit

            org.springframework
            spring-web
            ${spring.version}
        
        
            org.springframework

            org.springframework
            spring-context
            ${spring.version}
        

        
            org.springframework
            spring-beans
            ${spring.version}
        
        
            org.springframework
            spring-jdbc
            ${spring.version}

            org.springframework
            spring-tx
            ${spring.version}
        
        
            org.springframework.security
            spring-security-web
            4.1.3.RELEASE
        
        
            org.springframework.security
            spring-security-config
            4.1.3.RELEASE
        
    

SpringSecurity.xml配置

UserDetailService實現(xiàn)類

public class MyUserDetailService implements UserDetailsService  {

    @Override
    public UserDetails loadUserByUsername(String username)
            throws UsernameNotFoundException {
//在這里為了方便測試直接固定了
        MyUser myUser = new MyUser();
        System.out.println(username + "load的值");
        myUser.setUser_name("a");
        myUser.setUser_password("aa");
        myUser.setUser_role("ROLE_ADMIN");
        return new MyUserDetail(myUser, getAuthorities());
    }

    private Collection getAuthorities() {
        Collection grantedAuthorities = new ArrayList<>();
        SimpleGrantedAuthority grantedAuthority = new SimpleGrantedAuthority("ROLE_ADMIN");
        grantedAuthorities.add(grantedAuthority);
        return grantedAuthorities;
    }

}

MyUserDetail實現(xiàn)類：為了以后能更多的對用戶進行操作

public class MyUserDetail implements UserDetails {
    private MyUser myUser;
    private Collection authorities;

    public MyUserDetail(MyUser user,Collection authorities) {
        this.myUser = user;
        this.authorities = authorities;
    }

    @Override
    public Collection getAuthorities() {
        // TODO Auto-generated method stub
        return authorities;
    }

    @Override
    public String getPassword() {
        return myUser.getUser_password();
    }

    @Override
    public String getUsername() {
        return myUser.getUser_name();
    }

    @Override
    public boolean isAccountNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isEnabled() {
        // TODO Auto-generated method stub
        return false;
    }

AuthenticationProvider類

public class SecurityProvider implements AuthenticationProvider {
    @Autowired
    private MyUserDetailService userDetailsService;
    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {
        UsernamePasswordAuthenticationToken token = (UsernamePasswordAuthenticationToken) authentication;
        UserDetails userDetails = userDetailsService.loadUserByUsername("a");
        if (userDetails == null) {
            throw new UsernameNotFoundException("賬號不存在");
        }
        return new UsernamePasswordAuthenticationToken(userDetails, "aa",
                userDetails.getAuthorities());
    }

    @Override
    public boolean supports(Class authentication) {
        // TODO Auto-generated method stub
        return UsernamePasswordAuthenticationToken.class.equals(authentication);
    }

其他的正常配置即可
