TA貢獻(xiàn)1765條經(jīng)驗(yàn) 獲得超5個(gè)贊

這個(gè)報(bào)錯描述主要是這么兩句：

Error creating bean with name 'authenticationProcessingFilterEntryPoint' defined in ServletContext resource [/WEB-INF/classes/spring/applicationContext-security.xml]
這說明創(chuàng)建失敗是因?yàn)閯?chuàng)建一個(gè)叫authenticationProcessingFilterEntryPoint的bean失敗了，這個(gè)bean配置在applicationContext-security.xml，此時(shí)你就可以先從這個(gè)描述找到配置文件，然后找到相應(yīng)的類
No default constructor found; nested exception is java.lang.NoSuchMethodException: org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint.<init>()
LoginUrlAuthenticationEntryPoint
失敗的類叫LoginUrlAuthenticationEntryPoint，然后是沒有默認(rèn)的構(gòu)造函數(shù)

所以建議你先給LoginUrlAuthenticationEntryPoint加一個(gè)默認(rèn)的空的構(gòu)造函數(shù)，再啟動試試
