## 1. 找不到主清单属性 ##

build里面添加配置 配置启动类的路径

```java
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin </artifactId>
            <configuration>
                <fork>true</fork>
                <mainClass>per.czt.demo.educms.CmsApplication</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>

## 2. 读取不到mapper配置文件
    build里面添加配置 扫描resources
    
    ```xml
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>

## 3. 程序乱码问题 ##

properties里面添加配置

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    
    <maven.compiler.encoding>UTF-8</maven.compiler.encoding>

## 4. logback输出乱码 ##

logback.xml中  
pattern里面的颜色不能识别  
%yellow(%date\{yyyy-MM-dd HH:mm:ss\}) |%highlight(%-5level) |%blue(%thread) |%blue(%file:%line) |%green(%logger) |%cyan(%msg%n)  
解决：修改pattern  
%d\{yyyy-MM-dd HH:mm:ss.SSS\} %-5level \[%.15thread\] %logger\{36\}:%X\{sysUser\} - %.-4096msg%n

## 5. logback日志乱码 ##

去掉logback.xml文件中设置的字符集，因为默认使用gbk，设置后会导致错误

## 6. NoClassDefFoundError: javax/xml/bind/DatatypeConverter ##

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter  
at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1053)  
at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:942)  
at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1005)  
……  
由于缺少jaxb-api包导致的。在Java 8以及以前的版本，是默认包含jaxb这个jar包的；但是在java SE 9.0就不再包含着个包了，如果使用则需要手动引进。

引入javaxb依赖

<dependency>
                <groupId>javax.xml.bind</groupId>
                <artifactId>jaxb-api</artifactId>
                <version>2.3.0</version>
            </dependency>
            <dependency>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-impl</artifactId>
                <version>2.3.0</version>
            </dependency>
            <dependency>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-core</artifactId>
                <version>2.3.0</version>
            </dependency>
            <dependency>
                <groupId>javax.activation</groupId>
                <artifactId>activation</artifactId>
                <version>1.1.1</version>
            </dependency>
