idea使用问题总结

0.java等文件编译问题
如：

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):xxx

在pom.xml中build节点下面添加：

<!-- compile -->
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>

System.out.println(str);

快捷键

str.sout

智能提示

2.springboot项目 热部署
pom中添加devtools依赖

        <!-- 启动热部署 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
        </dependency>

bulid之后生效

偶尔修改后不生效则需要重启项目。
