Spring hybrid configuration, when you encounter the configuration file path NotFound, use Pathmatchingresourcepatternresolver to resolve

In the process of changing the XML configuration of spring to Java configuration, some problems have been encountered, and one problem with block time is that the path of the resource (. xml,. properties) is not found, Finally, it is solved by using pathmatchingresourcepatternresolver.

Background: Spring+mybatis

Entrance:

@Configuration @import ({        dalconfig. class         xxdbconfig. class  = {"Classpath*:spring/applicationcontext.xml", "Classpath*:spring-dao/applicationcontext.xml"})  Publicclass  Config {    @Bean    public  Pathmatchingresourcepatternresolver Pathmatchingresourcepatternresolver () {        returnNew  pathmatchingresourcepatternresolver ();    }}

Dalconfig

@Configuration Public classDalconfig {@Bean Publicdaldatasourcefactory Xxdaldatasource () {return Newdaldatasourcefactory (); } @Bean Publicpropertyplaceholderconfigurer Configbean (pathmatchingresourcepatternresolver pathmatchingresourcepattern Resolver)throwsIOException {List<Resource> resources =NewArraylist<>(); Resources.addall (Arrays.aslist (pathmatchingresourcepatternresolver.getresources ("Classpath*:config.properties"))); Resources.addall (Arrays.aslist (pathmatchingresourcepatternresolver.getresources ("Classpath*:/meta-inf/app.properties"))); Propertyplaceholderconfigurer Propertyplaceholderconfigurer=NewPropertyplaceholderconfigurer (); Propertyplaceholderconfigurer.setlocations (Resources.toarray (Newresource[resources.size ()]); Propertyplaceholderconfigurer.setignoreunresolvableplaceholders (true); returnPropertyplaceholderconfigurer; }}

Xxdbconfig

@Configuration Public classXxdbconfig {@Bean PublicDataSource datasourcexxxdb (@Value ("${dbdatacenter}") String Dbdatacenter, @Value ("${cfx_datasource_serviceurl}") String Cfxdatasourceserviceurl, @Value ("${app.id}") String appId, daldatasourcefactory xxxdaldatasource)throwsException {returnXxxxdaldatasource.createdatasource ("XXX" +Dbdatacenter, Cfxdatasourceserviceurl, appId); } @Bean PublicSqlsessionfactorybean sqlsessionfactoryxxxdb (DataSource datasourcexxxdb, PATHMATCHINGRESOURCEP Atternresolver pathmatchingresourcepatternresolver)throwsIOException {Sqlsessionfactorybean Sqlsessionfactorybean=NewSqlsessionfactorybean ();        Sqlsessionfactorybean.setdatasource (DATASOURCEXXXDB); Sqlsessionfactorybean.setmapperlocations (Pathmatchingresourcepatternresolver.getresources ("Classpath:com/xx/xxxdb/mapper/**/*.xml")//* * indicates iterative lookups        ); returnSqlsessionfactorybean; } @Bean Publicmapperscannerconfigurer mapperscannerconfigurerxxxdb () {mapperscannerconfigurer mapperscannerconfigurer=NewMapperscannerconfigurer (); returnMapperscannerconfigurer; }}

Test

 @RunWith (Springjunit4classrunner. Class  ) @ContextConfiguration (classes  =config. class  )   Class   dbconfigtest {@Autowired  private<    /span> ApplicationContext CTX;    @Autowired  private   environment env; @Test  public  void   Checkxxxdb () {mapperscannerconfigurer mapperscannerconfigurerxxxdb  = (mapperscannerconfigurer) Ctx.getBean (        "Mapperscannerconfigurerxxxdb" );    Assertnotnull (MAPPERSCANNERCONFIGURERXXXDB); }}
