user類中有個tag類的set集合;只從user類維護關(guān)系,一對多@OneToMany@JoinTable(name="shuo_tag",inverseJoinColumns=@JoinColumn(name="tag_id"),joinColumns=@JoinColumn(name="shuo_id"))privateSettags;Tag類中沒有維護關(guān)系然后我再html中[[${user}]]這樣獲取user就會出現(xiàn)以下這種錯誤java.lang.StackOverflowError:nullatjava.util.concurrent.ConcurrentHashMap.putVal(ConcurrentHashMap.java:1012)~[na:1.8.0_151]atjava.util.concurrent.ConcurrentHashMap.putIfAbsent(ConcurrentHashMap.java:1535)~[na:1.8.0_151]atjava.lang.ClassLoader.getClassLoadingLock(ClassLoader.java:463)~[na:1.8.0_151]atjava.lang.ClassLoader.loadClass(ClassLoader.java:404)~[na:1.8.0_151]atjava.lang.ClassLoader.loadClass(ClassLoader.java:411)~[na:1.8.0_151]atsun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335)~[na:1.8.0_151]atjava.lang.ClassLoader.loadClass(ClassLoader.java:357)~[na:1.8.0_151]atorg.thymeleaf.util.JavaScriptUtils.printObject(JavaScriptUtils.java:365)~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]atorg.thymeleaf.util.JavaScriptUtils.print(JavaScriptUtils.java:184)~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]atorg.thymeleaf.util.JavaScriptUtils.printArray(JavaScriptUtils.java:227)~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
