[jira] Created: (IBATIS-501) 2.3.1 throws exception for java bean
specification violation (2.3.0 not)
2.3.1 throws exception for java bean specification violation (2.3.0 not)
------------------------------------------------------------------------
Key: IBATIS-501
URL: https://issues.apache.org/jira/browse/IBATIS-501
Project: iBatis for Java
Issue Type: Bug
Components: SQL Maps
Affects Versions: 2.3.1
Environment: ibatis-2.3.1.710
Reporter: Kai Grabfelder
Assume the following class com.foo.bar.Bean with the following methods:
void setFoo(int)
void setFoo(String)
int getFoo()
I'm using this bean in an implicit parameter map as a parameter to an select statement that looks like this
<select id="getIds" parameterClass="java.util.Map" resultClass="java.lang.Integer">
select * from dual where 1 = #bean.foo#
</select>
with the bean being a property of the map. This statement is working with iBATIS 2.3.0 but iBATIS 2.3.1 throws the following exception when executing the select:
Could not get property 'foo' from com.foo.bar.Bean. Cause: java.lang.RuntimeException: Illegal overloaded setter method with ambiguous type for property foo in class class com.foo.bar.Bean. This breaks the JavaBeans specification and can cause unpredicatble results.
This exception makes sense when it comes to actually using the setters but as only the getters are used I think it should not be thrown. It is perfectly ok for me, if you consider this as won't fix, but please at least mention the change in the release notes because it breaks backward compatibility.
See below for the relevant parts of the stacktrace
