While some consider Java EE and Spring to be in competition, Spring is, in fact, complementary to Java EE. The Spring programming model does not embrace the Java EE platform specification; rather, it integrates with carefully selected individual specifications from the EE umbrella:并发
Spring 在 2003 年诞生,是对早期 J2EE 规范复杂性的响应。虽然有人认为 Java EE 和 Spring 相互竞争,实际上 Spring 是 Java EE 的补充。Spring 编程模型不包含 Java EE 平台规范,而是选择性的集成了一些单独的规则:框架
