@Qualifier @Retention(RUNTIME) @Target({METHOD,FIELD,PARAMETER}) public @interface ContextParam
The CDI annotation
@
ContextParam
allows you to inject aweb.xml
context parameter from the current application in a CDI managed bean. It's basically like@ManagedProperty("#{initParam['some.key']}") private String someKey;
in a "plain old" Faces managed bean.By default the name of the context parameter is taken from the name of the variable into which injection takes place. The example below injects the context parameter with name
foo
.@Inject @ContextParam private String foo;
The name can be optionally specified via the
name
attribute, which shall more often be used as context parameters may have a.o. periods and/or hyphens in the name, which are illegal in variable names. The example below injects the context parameter with namefoo.bar
into a variable namedbar
.@Inject @ContextParm(name="foo.bar") private String bar;
