我使用JPA AttributeConverter与spring boot 1.2.1 RELEASE并且它工作正常.但升级到spring boot 1.3.0.RELEASE后出现以下错误

我目前没有在POST JSON中设置serviceBeginTime和serviceEndTime.但是在升级spring boot版本之前,这并没有给我一个空指针.

转换器类

@Converter
public class TimestampPersistenceConverter implements AttributeConverter<Long, Timestamp> {


    @Override
    public …

我正在尝试将spring boot与OAuth2集成.通过以下https://github.com/royclarkson/spring-rest-service-oauth,我能够使用InMemoryStore来处理令牌.但是当我尝试使用JdbcTokenStore和postgres数据库实现它时,我得到了错误

 Handling error: BadSqlGrammarException, PreparedStatementCallback; bad SQL grammar [select token_id, token from oauth_access_token where authentication_id = ?]; nested exception is org.postgresql.util.PSQLException: ERROR: relation "oauth_access_token" does not exist

我检查了我的数据库,表存在.

网络安全配置

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private static PasswordEncoder encoder;

    @Autowired
    private CustomUserDetailsService userDetailsService;

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

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

    @Bean
    public PasswordEncoder passwordEncoder() {
        if(encoder == null) {
            encoder = …
