代码说明：

使用spring构建一个简单的工作流引擎，便于初学者了解工作流引擎的开发模式。-The API discussed here is bundled as the main source code under the src/java directory. Three unit tests exist in the src/testdirectory including SimpleSequenceTestCase, RateDropTestCase and PoolingTestCase. To run all the tests type "maven test" in a command shell and Maven will download all the necessary jar files before compiling and running. To see all output in the console, set maven.junit.usefile=false in the build.properties file. Otherwise, use all JUnit test output will be logged to the files under the target/test-reports dirctory. Actual XSL transforms will take place for two of the tests with results piped to output via log4j. After successful execution of the test suite, you may wish to run the tests individually and watch output real time. Try using "maven test:ui" to pull up the graphical test runer, the select the test you want to run and watch the output in the console.
