Does RestController scope affect handling of requests (behavior of request scope with default

问题 I am working on building an oAuth2 application using spring boot. However, there are various sample projects in Github using spring-security-oauth2 and spring-cloud-starter-oauth2 . Do we have specific scenarios where we can use a specific jar among both for an application? Though Spring cloud is mainly used for distributed systems. There are a lot of implementations on Github using spring-cloud-starter-oauth2 for even non-distributed applications. Thanks. 回答1: To resolve complex dependency

问题 I have this problem implementing a custom login authentication using SpringBoot and SpringBoot-Security. I made a Bitbucket repository as reference for this thread (within CustomSecuringWeb branch). Before anything else, most of the comments here follows the Securing a Web Application tutorial. The thing is, I was curious as how could the authentication data is now from the database instead of just memory data (which is very common in production line applications). Throughout the process I

问题 I'm building a spring boot application. Flyway database migrations are executed at the application startup. I decided to use two different roles: role__app ( read/write rights on tables, sequences in app schema) and role__migration ( advanced rights in app / migration schemas). Flyway migrations are executed under role__migration so it becomes the owner of the created objects. I thought that the following statements would help: ALTER DEFAULT PRIVILEGES IN SCHEMA app GRANT SELECT, INSERT,

问题 I have an application where the user will be uploading an excel file(.xlsx or .csv) with more than 10,000 rows with a single column "partId" containing the values to look for in database I will be reading the excel values and store it in list object and pass the list as parameter to the Spring Boot JPA repository find method that builds IN clause query internally: // Read excel file stream = new ByteArrayInputStream(file.getBytes()); wb = WorkbookFactory.create(stream); org.apache.poi.ss
