1. Introduction
In this tutorial, we’re going to take a look at the deprecated classes in Spring and Spring Boot and explain what these have been replaced with.
We’ll explore classes starting from Spring 4 and Spring Boot 1.4.
2. Deprecated Classes in Spring
For easier reading, we list classes and their replacements based on the Spring release. And, within each grouping of classes, we’ve sorted them by the class name, irrespective of package.
2.1. Spring 4.0.x
- org.springframework.cache.interceptor.DefaultKeyGenerator – replaced by the SimpleKeyGenerator or custom KeyGenerator implementations based on hash codes
- org.springframework.jdbc.support.lob.OracleLobHandler – DefaultLobHandler for the Oracle 10g driver and higher; we should consider it even against the Oracle 9i database
- org.springframework.test.AssertThrows – we should make use of JUnit 4’s @Test(expected=…) support instead
- org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter – AllEncompassingFormHttpMessageConverter
The following class was deprecated as of Spring 4.0.2, in favor of CGLIB 3.1’s default strategy, and was removed in Spring 4.1:
- org.springframework.cglib.transform.impl.MemorySafeUndeclaredThrowableStrategy
All deprecated classes, as well as deprecated interfaces, fields, methods, constructors, and enum constants for this Spring version can be found on the official documentation page.
2.2. Spring 4.1.x
- org.springframework.jdbc.core.simple.ParameterizedBeanPropertyRowMapper – BeanPropertyRowMapper
