创建名为“springSecurityFilterChain”的 bean 时出错位置：22

Question

我正在尝试进行第一次防御。但是我马上就遇到了错误。我已经在数据库中创建了所有的表和字段，所以错误与名称拼写错误无关。

配置中的方法

        @Bean
    public JdbcUserDetailsManager users(DataSource dataSource) {
        UserDetails user = User.builder()
                .username("user")
                .password("{bcrypt}$2y$12$0./a1TvfPwxj.OTlQLF1HONCpHXHtrcrn7CR5sPE7UHSWLbkPjxZG")
                .roles("USER")
                .build();
        UserDetails admin = User.builder()
                .username("admin")
                .password("{bcrypt}$2y$12$0./a1TvfPwxj.OTlQLF1HONCpHXHtrcrn7CR5sPE7UHSWLbkPjxZG")
                .roles("ADMIN", "USER")
                .build();
        JdbcUserDetailsManager jdbcUserDetailsManager = new JdbcUserDetailsManager(dataSource);
        if (jdbcUserDetailsManager.userExists(user.getUsername())) {
            jdbcUserDetailsManager.deleteUser(user.getUsername());
        }
        if (jdbcUserDetailsManager.userExists(admin.getUsername())) {
            jdbcUserDetailsManager.deleteUser(admin.getUsername());
        }
        jdbcUserDetailsManager.createUser(user);
        jdbcUserDetailsManager.createUser(admin);
        return jdbcUserDetailsManager;
    }

其中一个特点是 org.springframework.boot 插件中的红色突出显示

看起来你的密码有问题。试试这样

@Autowired
private PasswordEncoder passwordEncoder;
...
UserDetails user = User.withUsername("myusername")
  .password(passwordEncoder.encode("mypassword"))
  .roles("ROLE_USER")
  .build();
