Oauth2 server 搭建

• 添加表sys_user的service、mapper

@Mapper
public interface UserMapper {

    @Insert("INSERT INTO sys_user(id,name,username,password,tel,gender,createTime) VALUES(#{id},#{name},#{username},#{password},#{tel},#{gender},#{createTime})")
    void insert(User user);

    @Delete("DELETE FROM sys_user WHERE id = #{id}")
    void delete(Long id);

    @Update("UPDATE sys_user SET name=#{name},username=#{username},password=#{password},tel=#{tel},gender=#{gender},createTime=#{createTime} WHERE id =#{id}")
    int update(User user);

    @ResultMap("BaseResultMap")
    @Select("SELECT * FROM sys_user WHERE id=#{id}")
    User findById(Long id);

    @ResultMap("BaseResultMap")
    @Select("SELECT * FROM sys_user WHERE username=#{username}")
    User findByUsername(String username);

    @ResultMap("BaseResultMap")
    @Select("SELECT * FROM sys_user WHERE tel=#{tel}")
    User findByTel(String tel);

    @ResultMap("BaseResultMap")
    @Select("SELECT * FROM sys_user")
    List<User> findAll();

    @ResultMap("BaseResultMap")
    @Select("SELECT * FROM sys_user WHERE name like #{name}")
    List<User> findByName(String name);

}

@Service
public class UserServiceImpl implements UserService {

    @Resource
    UserMapper mapper;

    @Override
    public User save(User user) {
        if(user.getId()!=null){
            mapper.update(user);
        } else {
            user.setId(System.currentTimeMillis());
            mapper.insert(user);
        }
        return user;
    }

    @Override
    public User findById(Long id) {
        return mapper.findById(id);
    }

    @Override
    public User findByUsername(String username) {
        return mapper.findByUsername(username);
    }

    @Override
    public User findByTel(String tel) {
        return mapper.findByTel(tel);
    }

    @Override
    public List<User> findAll() {
        return mapper.findAll();
    }

    @Override
    public void delete(Long id) {
        mapper.delete(id);
    }

    @Override
    public List<User> findByName(String name) {
        return mapper.findByName("%" + name + "%");
    }

}

• 添加登录拦截

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public UserDetailsService simpleUserDetailsService(){
        return new UserDetailsServiceImpl();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(simpleUserDetailsService());
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.userDetailsService(userDetailsService());
        http.csrf().disable();
        http.formLogin()
                .loginPage("/signin").loginProcessingUrl("/signin/form/account").defaultSuccessUrl("/index")
                .and()
                .logout().logoutUrl("/signout").logoutSuccessUrl("/signin")
                .and()
                .authorizeRequests()
                .antMatchers("/signin","/signin/form/tel","/code/image","/code/mobile","/static/**").permitAll()
                .antMatchers("/oauth/**").permitAll()
                .antMatchers("/user/**").hasAnyRole("USER","ADMIN")
                .anyRequest().authenticated();

    }

}

• 添加登录表单signin.html

<div class="tab-pane fade in active" id="account-login">
    <form th:action="@{/signin/form/account}" method="post">
        <label for="username" class="sr-only">用户名</label>
        <input class="form-control" type="text" name="username" id="username" value="user" placeholder="账号" required>
        <label for="password" class="sr-only">密码</label>
        <input class="form-control" type="password" name="password" id="password" value="123456" placeholder="密码" required>
        <button class="btn btn-lg btn-primary btn-block" type="submit">登录</button>
    </form>
</div>

• Oauth2 server Config

        endpoints.authenticationManager(authenticationManager);
    }

    @Override
