方法详细资料

matches

boolean matches(Predicate<String> activeProfiles)

Test if this Profiles instance matches against the given active profiles predicate.

参数:

activeProfiles - a predicate that tests whether a given profile is currently active

of

static Profiles of(String... profiles)

Create a new Profiles instance that checks for matches against the given profile strings.

The returned instance will match if any one of the given profile strings matches.

A profile string may contain a simple profile name (for example "production") or a profile expression. A profile expression allows for more complicated profile logic to be expressed, for example "production & cloud".

The following operators are supported in profile expressions.

• ! - A logical NOT of the profile or profile expression
• & - A logical AND of the profiles or profile expressions
• | - A logical OR of the profiles or profile expressions

Please note that the & and | operators may not be mixed without using parentheses. For example "a & b | c" is not a valid expression; it must be expressed as "(a & b) | c" or "a & (b | c)".

Two Profiles instances returned by this method are considered equivalent to each other (in terms of equals() and hashCode() semantics) if they are created with identical profile strings.

参数:

profiles - the profile strings to include

返回:

a new Profiles instance
