springboot ConditionalOnBean.parameterizedContainer on overloading @bean method, it will expression ambiguous behavior

when i test the parameterizedContainer annotation parameter on overloading @Bean method. found that the first bean method init more than once，but another never init。 code like this：

/**

 * @date 2020-01-17

@Configuration
public class ConditionOnBeanTest {

    @Bean(name = "testBean1")
    @ConditionalOnBean(parameterizedContainer = {List.class})
    public List<ConditionOnBeanTest> testBean(int intParameterTest, long longParameterTest) {
        System.out.println("testListStringBean -- intParameterTest");
        return Collections.singletonList(new ConditionOnBeanTest());
    }

    @Bean(name = "testBean2")
    @ConditionalOnBean(parameterizedContainer = {List.class})
    public List<ConditionOnBeanTest> testBean(String stringParameterTest) {
        System.out.println("testListStringBean -- stringParameterTest");
        return Collections.singletonList(new ConditionOnBeanTest());
    }

    @Bean
    public String testStringBean() {
        System.out.println("testStringBean");
        return "testStringBean";
    }

    @Bean
    public int testIntBean() {
        System.out.println("testIntBean");
        return 812;
    }

    @Bean
    public long testLongBean() {
        System.out.println("testLongBean");
        return 8120L;
    }

}

As mentioned in the Javadoc you should only use @ConditionOnBean for auto-configuration classes. Furthermore, it doesn't really make sense to try and use it within the context of a single configuration class.
