架构师之maven(三)---------junit测试可能遇到的问题

1.前言.
  如题.
2.代码.
(1)类型转换错误
(1)问题描述

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error resolving JdbcType. Cause: java.lang.IllegalArgumentException: No enum const class org.apache.ibatis.type.JdbcType.Integer

解决办法

Integer 改为INTEGER 这个是个枚举,和大小写有关-_-!

(2)无法autowire.
很可能你的工程的pom没有引入配置文件xml等.pom.xml的build节点加上.

<build>
  		<plugins>
  			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>cobertura-maven-plugin</artifactId>
				<version>2.5.1</version>
			</plugin>
			
  			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-source-plugin</artifactId>
				<executions>
					<execution>
						<id>attach-sources</id>
						<goals>
							<goal>jar</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
  		</plugins>
  		
		<filters>
			<filter>src/main/filter/${env}.properties</filter>
		</filters>
		<resources>
		<resource>
			<directory>src/main/resources</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
					<include>**/*.ftl</include>
				</includes>
				<filtering>true</filtering>
			</resource>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.xml</include>
				</includes>
				<filtering>true</filtering>
			</resource>
		</resources>
	</build>

(3)不是类问题,始终imcomlabe class报错.
  maven update--->看test类是不是在builder folder里面--->检查service或者mapper是不是有语法错误--->数据库或者xml是否正确--->再执行下.
