我一直试图从
运行Spring Batch Hello World 3示例http://jroller.com/0xcafebabe/entry/spring_batch_hello_world_3
我错过了一些罐子，有人帮助我，让项目更好地工作，但我仍然有错误......有人可以帮助我：
这是我的applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

这是我在控制台上遇到的错误

答案 0 :(得分：2)
看起来SimpleJobRepository的API在1.1.2和1.1.3之间发生了变化（引入向后不兼容的更改IMHO的糟糕时刻）。
您正在使用的教程使用Spring Batch 1.1.1，其中上面的类有一个带three parameters的构造函数。现在它有四个。额外参数是ExecutionContextDao。
这是我完全未经测试的解决方案：
<bean id="jobRepository" class="org.springframework.batch.core.repository.support.SimpleJobRepository">
<constructor-arg>
<bean class="org.springframework.batch.core.repository.dao.MapJobInstanceDao"/>
</constructor-arg>
<constructor-arg>
<bean class="org.springframework.batch.core.repository.dao.MapJobExecutionDao" />
</constructor-arg>
<constructor-arg>
<bean class="org.springframework.batch.core.repository.dao.MapStepExecutionDao"/>
</constructor-arg>
<constructor-arg> <!-- Extra constructor argument -->
<bean class="org.springframework.batch.core.repository.dao.MapExecutionContextDao"/>
</constructor-arg>
</bean>
从未使用过Spring Batch，但也许您可以使用更新的教程（我不建议降级为1.x）？
