When querying database information by parameter name using the HQL statement, "=:" cannot have spaces between parameters, otherwise it will error

Problem Description:

Today, when using HQL to query database information according to the name of the parameter, the error is as follows:

Org.hibernate.QueryException:Space is isn't allowed after parameter prefix ': ' [from Users user where user.address=: UserAddress] at Org.hibernate.engine.query.spi.ParameterParser.parse (Parameterparser.java:95) at Org.hibernate.engine.query.spi.ParamLocationRecognizer.parseLocations (Paramlocationrecognizer.java: 75) at Org.hibernate.engine.query.spi.HQLQueryPlan.buildParameterMetadata (Hqlqueryplan.java:289) at Org.hibernate.engine.query.spi.HQLQueryPlan.<init> (hqlqueryplan.java:124) at Org.hibernate.engine.query.spi.HQLQueryPlan.<init> (hqlqueryplan.java:80) at Org.hibernate.engine.query.spi.QueryPlanCache.getHQLQueryPlan (Queryplancache.java:168) at Org.hibernate.internal.AbstractSessionImpl.getHQLQueryPlan (Abstractsessionimpl.java:219) at Org.hibernate.internal.AbstractSessionImpl.createQuery (Abstractsessionimpl.java:197) at Org.hibernate.internal.SessionImpl.createQuery (Sessionimpl.java:1736) at Sun.reflect.NativeMethodAccessorImpl.invoke0 (Native Method) at Sun.reflect.NativeMethodAccessorImpl.invoke (Nativemethodaccessorimpl.java:39) at Sun.reflect.DelegatingMethodAccessorImpl.invoke (Delegatingmethodaccessorimpl.java:25) at Java.lang.reflect.Method.invoke (Method.java:597) at Org.hibernate.context.internal.threadlocalsessioncontext$transactionprotectionwrapper.invoke ( Threadlocalsessioncontext.java:65W) at $Proxy 9.createQuery (Unknown Source) at Com.hibernate.HibernateSessionFactory.getQuery (hibernatesessionfact Ory.java:72) at Com.hibtest.entity.TestUsers.queryByNane (Testusers.java:217) at Sun.reflect.NativeMethodAccessorImpl.invoke0 (Native Method) at Sun.reflect.NativeMethodAccessorImpl.invoke (Nativemethodaccessorimpl.java:39) at Sun.reflect.DelegatingMethodAccessorImpl.invoke (Delegatingmethodaccessorimpl.java:25) at Java.lang.reflect.Method.invoke (Method.java:597) at org.junit.runners.model.frameworkmethod$1.runReflectiveCall (frameworkmethod.java:45) at Org.junit.internal.runners.model.ReflectiveCallable.run (Reflectivecallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively (Frameworkmethod.java:42) at Org.junit.internal.runners.statements.InvokeMethod.evaluate (Invokemethod.java:20) at Org.junit.runners.ParentRunner.runLeaf (Parentrunner.java:263) at Org.junit.runners.BlockJUnit4ClassRunner.runChild (Blockjunit4classrunner.java:68) at Org.junit.runners.BlockJUnit4ClassRunner.runChild (Blockjunit4classrunner.java:47) at org.junit.runners.parentrunner$3.run (parentrunner.java:231) at org.junit.runners.parentrunner$1.schedule (parentrunner.java:60) at Org.junit.runners.ParentRunner.runChildren (Parentrunner.java:229) at org.junit.runners.parentrunner.access$(parentrunner.java:50) at org.junit.runners.parentrunner$2.evaluate (parentrunner.java:222) at Org.junit.runners.ParentRunner.run (Parentrunner.java:300) at Org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run (Junit4testreference.java:50) at Org.eclipse.jdt.internal.junit.runner.TestExecution.run (Testexecution.java:38) at Org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests (Remotetestrunner.java:467) at Org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests (Remotetestrunner.java:683) at Org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run (Remotetestrunner.java:390) at Org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main (Remotetestrunner.java:197)

The reason for this is that I have added extra space on both sides of the "=:" When I write the HQL statement, which causes the error to occur.

When querying database information by parameter name using the HQL statement, "=:" cannot have spaces between parameters, otherwise it will error
