at …Spring boot升级报错
Spring Boot应用程序升级到2.6.0后由于循环依赖而无法启动
Error creating bean with name 'securityConfig':

unresolvable circular reference?
Lombok添加lib后出现如下错误
An error has occurred. See error log for more details.

每当行更新时，是否可以使用“生成的列”在 PostgreSQL 中使用“current_timestamp”（自动）更新列？
目前我正在使用触发器来更新审计字段last_update_date。但我打算切换到生成的列
ALTER TABLE test ADD COLUMN last_update_date timestamp without time zone
GENERATED ALWAYS AS (current_timestamp) STORED;
更改列时出现错误
ERROR: generation expression is not immutable
Julia Computing 提供的 Julia 和 Julia Pro 有什么区别？
Julia Pro 是否有任何在 Julia 中不可用的企业库？
升级到spring-cloud版本后，spring-cloud-config-client无法从spring-cloud-config-server读取配置文件2.4.02020.0.0-M6
查询对象，
Student student = return jdbcTemplate.queryForObject("select * from student_id = ?", new Object[] { studentId }, studentRowMapper);
对于查询，
List<Student> students = return jdbcTemplate.query("select * from class_room_id = ?", new Object[] { classRoomId }, studentRowMapper);
双方jdbcTemplate.queryForObject并jdbcTemplate.query在上面春季启动2.4.X已被弃用

createExpressionHandler目前，我已经通过覆盖GlobalMethodSecurityConfiguration. 代码是
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {
Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private ApplicationContext applicationContext;
@Override
protected MethodSecurityExpressionHandler createExpressionHandler() {
CustomMethodSecurityExpressionHandler expressionHandler = new CustomMethodSecurityExpressionHandler();
expressionHandler.setPermissionEvaluator(new CustomPermissionEvaluator());
expressionHandler.setApplicationContext(applicationContext);
return expressionHandler;
}
}
-- CustomMethodSecurityExpressionHandler 类
public class CustomMethodSecurityExpressionHandler extends DefaultMethodSecurityExpressionHandler {
private ApplicationContext applicationContext;
private AuthenticationTrustResolver trustResolver = new AuthenticationTrustResolverImpl();
@Override
protected MethodSecurityExpressionOperations createSecurityExpressionRoot(Authentication authentication,
MethodInvocation invocation) {
CustomMethodSecurityExpressionRoot root = new CustomMethodSecurityExpressionRoot(authentication);
root.setPermissionEvaluator(getPermissionEvaluator());
root.setTrustResolver(this.trustResolver);
root.setRoleHierarchy(getRoleHierarchy());
root.setG(this.applicationContext.getBean(CustomTraversalSource.class));
return root;
