package contains
CollaborativeFilter.java
lesson9
package contains
ContentBasedFilter.java
Case 1:
//SpringBootApplication
(commented)
ComponentScan(basePackages=“io.datajek.spring.basics.movierecommendersystem.lesson10”)
ComponentScan(includeFilters =
@ComponentScan.Filter
(type= FilterType.REGEX, pattern=“io.datajek.spring.basics.movierecommendersystem.lesson9.*”))
In this case : CollaborativeFilter bean found = false
ContentBasedFilter bean found = false.
Case 2 :
SpringBootApplication
(Uncommented)
ComponentScan(basePackages=“io.datajek.spring.basics.movierecommendersystem.lesson10”)
ComponentScan(includeFilters =
@ComponentScan.Filter
(type= FilterType.REGEX, pattern=“io.datajek.spring.basics.movierecommendersystem.lesson9.*”))
In this case : CollaborativeFilter bean found = True.
ContentBasedFilter bean found = True.
Case 3 :
//SpringBootApplication
(commented)
//ComponentScan(basePackages=“io.datajek.spring.basics.movierecommendersystem.lesson10”) (commented)
ComponentScan(includeFilters =
@ComponentScan.Filter
(type= FilterType.REGEX, pattern=“io.datajek.spring.basics.movierecommendersystem.lesson9.*”))
In this case : CollaborativeFilter bean found = false.
ContentBasedFilter bean found = True.
My question is why we are getting
true
for
ContentBasedFilter bean
in
case 3
when //SpringBootApplication annotation is (commented) ,
but in
case 1
we are getting
false
for both beans
when //SpringBootApplication annotation is (commented)
please explain when do we need to include
SpringBootApplication
and when not too.
According to me we should get true , true for case 1.
