一、问题描述：
搭建hibernate环境时，使用hibernate-distribution-3.3.1.GA-dist和slf4j-1.7.7。配置文件和程序OK之后，运行程序出现如下问题：
1 java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory 2 at org.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:60) 3 at org.hibernate.cfg.Configuration.<clinit>(Configuration.java:151) 4 at com.pers.test.CustomerTest.<clinit>(CustomerTest.java:33) 5 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) 6 at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) 7 at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) 8 at java.lang.reflect.Constructor.newInstance(Constructor.java:423) 9 at org.junit.runners.BlockJUnit4ClassRunner.createTest(BlockJUnit4ClassRunner.java:217) 10 at org.junit.runners.BlockJUnit4ClassRunner$1.runReflectiveCall(BlockJUnit4ClassRunner.java:266) 11 at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) 12 at org.junit.runners.BlockJUnit4ClassRunner.methodBlock(BlockJUnit4ClassRunner.java:263) 13 at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) 14 at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) 15 at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) 16 at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) 17 at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) 18 at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) 19 at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) 20 at org.junit.runners.ParentRunner.run(ParentRunner.java:363) 21 at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) 22 at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) 23 at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) 24 at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) 25 at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) 26 at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)
二、原因分析：jar包版本冲突
类 org.slf4j.impl.StaticLoggerBinder在hibernate-distribution-3.3.1.GA-disthibernate-distribution-3.3.1.GAlib equiredslf4j-api-1.5.2.jar中是类的公有静态变量:
public static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();
而在slf4j-1.7.7slf4j-log4j12-1.7.7.jar中是私有变量:
private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();
解决方案：1.修改slf的源代码，将这个变量由私有改为公有，再打包，问题可解决。
2. 将slf4j-api-1.5.2.jar替换为slf4j-1.7.7slf4j-api-1.7.7.jar，问题可解决。
三、jar包附图
如果需要注解或和其他框架整合，则另行导入，各jar作用不再赘述。
