Annotation Type HttpConstraint

@Documented
@Retention(value=RUNTIME)
public @interface HttpConstraint

This annotation is used within the ServletSecurity annotation to represent the security constraints to be applied to all HTTP protocol methods for which a corresponding HttpMethodConstraint element does NOT occur within the ServletSecurity annotation.

Since:

Servlet 3.0

Optional Element Summary

String[]	rolesAllowed The names of the authorized roles.
ServletSecurity.TransportGuarantee	transportGuarantee The data protection requirements (i.e., whether or not SSL/TLS is required) that must be satisfied by the connections on which requests arrive.
ServletSecurity.EmptyRoleSemantic	value The default authorization semantic.

value

public abstract ServletSecurity.EmptyRoleSemantic value

The default authorization semantic. This value is insignificant when rolesAllowed returns a non-empty array, and should not be specified when a non-empty array is specified for rolesAllowed.

Returns:

the ServletSecurity.EmptyRoleSemantic to be applied when rolesAllowed returns an empty (that is, zero-length) array.

Default:

javax.servlet.annotation.ServletSecurity.EmptyRoleSemantic.PERMIT

transportGuarantee

public abstract ServletSecurity.TransportGuarantee transportGuarantee

The data protection requirements (i.e., whether or not SSL/TLS is required) that must be satisfied by the connections on which requests arrive.

Returns:

the ServletSecurity.TransportGuarantee indicating the data protection that must be provided by the connection.

Default:

javax.servlet.annotation.ServletSecurity.TransportGuarantee.NONE

rolesAllowed

public abstract String[] rolesAllowed

The names of the authorized roles. Duplicate role names appearing in rolesAllowed are insignificant and may be discarded during runtime processing of the annotation. The String "*" has no special meaning as a role name (should it occur in rolesAllowed).

Returns:

an array of zero or more role names. When the array contains zero elements, its meaning depends on the EmptyRoleSemantic returned by the value method. If value returns DENY, and rolesAllowed returns a zero length array, access is to be denied independent of authentication state and identity. Conversely, if value returns PERMIT, it indicates that access is to be allowed independent of authentication state and identity. When the array contains the names of one or more roles, it indicates that access is contingent on membership in at least one of the named roles (independent of the EmptyRoleSemantic returned by the value method).

Default:

{}
