——在看到这些个问题的时候,日志基本都会告诉你错误的地方,所以我们大部分可以根据日志报错的信息分析错误的原因:
一、编译出问题
仔细看报出的问题,有没有如:“Description:…” 这样的字眼,没有 “描述”,如上图所示,这种情况下的操作:
1.clean清理一下; 2.然后install重新编译一下 ;
3.也可以用这个命令,重新编译一下
这个时候重新启动,如果还是报同样的错误,打开如下图位置,看是否有编译的文件,如mapper.xml文件,application.yml或者application.properties文件,以及一些配置文件等
——哎!生气,这里发现真的没有mapper和配置文件,只有main下面的.jar文件,该怎么办呢?
——pom.xml文件中给加入要编译的文件位置依赖,如下:(这是我的文件位置,你根据你的进行调整)
<!--引入本地资源-->
<resources>
<!--加载lib文件,特殊情况下会有lib,但大部分都靠依赖下载了-->
<resource>
<directory>lib</directory>
<targetPath>BOOT-INF/lib/</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>
<!--打jar包-->
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
</resource>
<!--将properties和xml文件编译-->
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
好的,清理——>打包——>启动——>运行成功,搞定收工
二、请求接口重复
根据日志看出它说路径问题;这样想你写的接口名字是否重复,只有一个斜杠或者没斜杠的情况
如下截图:
修改如下:
好的,重新启动,搞定收工
三、加@Mapper注解
这些情况就是看描述的问题
如图:
这种情况,看是不是没有扫描到它需要的东西,给加上@Mapper注解(是扫描dao层的),或者 加上@Service注解(扫描service层)即可。
四、加@SpringBootApplication注解,数据库问题
根据问题看出:springboot启动时会自动注入数据源和配置jpa ,解决:
在@SpringBootApplication中排除其注入
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
五、端口重复问题
查看是否自己的运行端口冲突,将其kill杀死,重新启动,或者跟换端口
以下是查看端口冲突的方式:
-
window键+R,输入“netstat -aon|findstr 8080”找到占用8080端口的进程号:
2.输入“tasklist|findstr “3412” ”:查看进程号为“3412”的进程:
3.输入“taskkill /f /t /im QQ.exe”:(/f:强制性的结束进程)结束这个进程
现在可以重新启动一下,看是否运行成功
六、包冲突
还有的情况可能是包冲突了,可以将maven仓库清理一下自己的包,重新下载一下
希望可以帮助到您
