Field authenticationManager in com.spring.cloud.authentic.config.JwtAuthorizationConfig required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.

沒有AuthenticationManager 這個bean 無法注入

在securityconfig類中注入

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

Failed to instantiate [org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter]: Factory method 'jwtAccessTokenConverter' threw exception; nested exception is java.lang.IllegalArgumentException: [Assertion failed] - this String argument must have text; it must not be null, empty, or blank

 [Assertion failed] - this String argument must have text; it must not be null, empty, or blank

檢查資料庫連線。一般都是資料庫連線不上
