Package org.springframework.r2dbc

@NullMarked package org.springframework.r2dbc

The classes in this package make R2DBC easier to use and reduce the likelihood of common errors. In particular, they:

• Simplify error handling, avoiding the need for resource management blocks in application code.
• Present exceptions to application code in a generic hierarchy of unchecked exceptions, enabling applications to catch data access exceptions without being dependent on R2DBC, and to ignore fatal exceptions there is no value in catching.
• Allow the implementation of error handling to be modified to target different RDBMSes without introducing proprietary dependencies into application code.
