2017-3-16 · Use Type-Safe SQL Parameters. The Parameters collection in SQL Server provides type checking and length validation. If you use the Parameters collection, input is treated as a literal value instead of as executable code. An additional benefit of using the Parameters collection is that you can enforce type and length checks. Values outside the range will trigger an exception.

Another solution commonly proposed for dealing with SQL injection attacks is to use stored procedures. Although stored procedures prevent some types of SQL injection attacks, they do not protect against many others. For example, the following PL/SQL procedure is vulnerable to the same SQL injection attack shown in the first example.

I believe this transformation takes place when the Spring beans are initializing which is also before your own code is actually executed. Or put another way, your query must be ready by bean initialization time, minus the prepared parameters.

2021-7-16 · That’s a good question. In CDI the process of matching a bean to an injection point is type-safe.Each bean declares a set of bean types. In our example above, the Translator bean has two bean types: Translator and java.lang.Object.Subsequently, a bean is assignable to an injection point if the bean has a bean type that matches the required type and has all the required qualifiers.
