记录一次SpringCloud maven打包中遇到的问题

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

<!-- 文件拷贝时的编码 -->
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<!-- 编译时的编码 -->
<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 HHss}) |%highlight(%-5level) |%blue(%thread) |%blue(%file:%line) |%green(%logger) |%cyan(%msg%n)
解决：修改pattern
%d{yyyy-MM-dd HHss.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

<!--             设置字符集 -->
<!--            <charset>UTF-8</charset>-->

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>
