Java SpringDBUnit容错Delta-断言浮点数

我对SpringDBunit中的浮点断言有问题。我读过这篇文章，但我使用的是MySql，无法更改DB层。我也检查过了，但也没有运气，仍然得到断言错误：

junit.framework.ComparisonFailure: value (table=tablename, row=0, col=colname) 
Expected :0.35
Actual   :0.35000000000000003

有没有办法在SpringDBUnit中设置断言的“容差”

我的MySqlDataFactory如下所示：

//MySqlDataTypeFactory is taken from a context
ToleratedDeltaMap.ToleratedDelta toleratedDelta = new ToleratedDeltaMap.ToleratedDelta("tablename","colname",0.001);
mySqlDataTypeFactory.addToleratedDelta(toleratedDelta);

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory" value="#{testDataTypeFactory.getMySqlDataTypeFactory()}" />-
</bean>

而

DatabaseConfigBean

在上下文中定义如下：

//MySqlDataTypeFactory is taken from a context
ToleratedDeltaMap.ToleratedDelta toleratedDelta = new ToleratedDeltaMap.ToleratedDelta("tablename","colname",0.001);
mySqlDataTypeFactory.addToleratedDelta(toleratedDelta);

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory" value="#{testDataTypeFactory.getMySqlDataTypeFactory()}" />-
</bean>
