多使用一個(gè)注解報(bào)錯(cuò)，當(dāng)我注釋掉私有變量上的autowired的注解，只是用service注解時(shí)，就不報(bào)錯(cuò)了，求解釋

我猜測會(huì)不會(huì)是你的注解的成員變量的變量名有問題。

很明顯injectionServiceImpl注入的時(shí)候沒有找到對(duì)應(yīng)類，報(bào)了?NoSuchBeanDefinitionException，猜想是injectionServiceImpl上的autowired去掉后（spring就不去找這個(gè)類而已），這個(gè)變量沒有被注入，只是一個(gè)null；樓主只是沒有使用這個(gè)對(duì)象所以沒有發(fā)現(xiàn)。希望可以給你一些參考
