SpringMVC、Spring、Hibenrtae整合程序

2017.01.11 22:01 2481浏览

前言 ：整合项目利用Maven构建,如果有小伙伴对Maven不是很了解的话请戳这里。

  1. 开发工具 IDEA
  2. JDK1.7 64位
  3. Mysql5.6
  4. Spring 3.2.4
  5. Hibernate 3.6
  6. Maven 3.3

首先利用开发工具搭建一个项目



添加项目依赖[ps:在这里依赖就是需要用到的jar包]
这边我直接放上pom文件的详细内容了

        The following attributes are required:

        maxElementsInMemory            - Sets the maximum number of objects that will be created in memory
        eternal                        - Sets whether elements are eternal. If eternal,  timeouts are ignored and the
        element is never expired.
        overflowToDisk                 - Sets whether elements can overflow to disk when the in-memory cache
        has reached the maxInMemory limit.

        The following attributes are optional:
        timeToIdleSeconds              - Sets the time to idle for an element before it expires.
        i.e. The maximum amount of time between accesses before an element expires
        Is only used if the element is not eternal.
        Optional attribute. A value of 0 means that an Element can idle for infinity.
        The default value is 0.
        timeToLiveSeconds              - Sets the time to live for an element before it expires.
        i.e. The maximum time between creation time and when an element expires.
        Is only used if the element is not eternal.
        Optional attribute. A value of 0 means that and Element can live for infinity.
        The default value is 0.
        diskPersistent                 - Whether the disk store persists between restarts of the Virtual Machine.
        The default value is false.
        diskExpiryThreadIntervalSeconds- The number of seconds between runs of the disk expiry thread. The default value
        is 120 seconds.
