Spring MVC アプリケーション内で JUnit テストを実行する際の問題。テスト 1 (insertTweet) は正常に実行されているようですが、テスト 2 で "LazyInitializationException" 例外が発生します (以下の完全な stactrace を参照)。スローされる理由は理解していますが、セッションが閉じている理由と、すべてのテスト 2 の開始時にセッションを再度開く方法がわかりません (または、残りのテストが完了するまで既存のセッションを開いたままにします)。テスト クラスとともにスローされた StackTrace 全体を貼り付けました。

@Transactionalあなたのテストメソッドに追加してください

ええ、私は問題を解決しました：

        @RunWith(SpringJUnit4ClassRunner.class)
        @ContextConfiguration(locations = { "classpath*:applicationContext.xml"})
        @Transactional
        public class UserinfoActionTest extends StrutsSpringJUnit4TestCase<UserinfoAction> {
                @Test
            public void testLogin2(){
                          request.setParameter("jsonQueryParam", param);
                String str = null;
        try {

                    str = executeAction("/login.action");
                    HashMap<String,List<TUserinfo>> map = (HashMap<String,List<TUserinfo>>)findValueAfterExecute("outDataMap"); }
 catch (Exception e) {
                    e.printStackTrace();
                }

            }


        @Controller
        @Results({  
            @Result(name="json",type="json"
                    , params={"root","outDataMap","excludeNullProperties","true"
                            ,"excludeProperties","^ret\\[\\d+\\]\\.city\\.province,^ret\\[\\d+\\]\\.enterprise\\.userinfos","enableGZIP","true"
                    })
        })
        public class UserinfoAction extends BaseAction {
                    @Action(value="login")

            public String login(){
                if(jsonQueryParam!=null && jsonQueryParam.length()>0)
                {
                    user = JsonMapper.fromJson(jsonQueryParam, TUserinfo.class);
                }
                Assert.notNull(user);
                 //RESULT="ret" addOutJsonData: put List<TUserinfo> into outDataMap with key RESULT for struts2 JSONResult  
                addOutJsonData(RESULT, service.login(user));
                return JSON;
            }
