Scopes of beans

Producing a singleton

Report a typo

In which cases do we produce a singleton-scoped bean?

Java

// A    
@Bean
public SomeBean createBean() { /* ... */ }

// B   
@Bean
@Scope("prototype")
public SomeBean createBean() { /* ... */ }

// C   
@Bean
@Scope("singleton")
public SomeBean createBean() { /* ... */ }

// D  
@Bean
@Scope("application")
public SomeBean createBean() { /* ... */ }

Kotlin

// A
@Bean
fun createBean(): SomeBean { /* ... */ }

// B
@Bean
@Scope("prototype")
fun createBean(): SomeBean { /* ... */ }

// C
@Bean
@Scope("singleton")
fun createBean(): SomeBean { /* ... */ }

// D
@Bean
@Scope("application")
fun createBean(): SomeBean { /* ... */ }
