一、springboot 打包打小包

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <!-- <configuration>
                    <fork>true</fork>
                </configuration> -->
                
                <configuration>
                    <fork>false</fork>
                 </configuration>
            </plugin>
        </plugins>
    </build>

设置为true 就是打小包，false 原来的包

二、mybatis 逆向工程使用

CommentVoExample commentVoExample = new CommentVoExample();

// 设置条件
commentVoExample.createCriteria().andCidEqualTo(cid).andStatusEqualTo("approved");

// 排序
 commentVoExample.setOrderByClause("coid desc");

设置条件和 排序的使用

三、接口返回

package cn.com.connext.authority.utils;

public class LYResultVO {

    private Object obj;
    /** 0 表示成功 1 是失败*/
    private int state;
    private String msg;
    
    public Object getObj() {
        return obj;
    }
    public void setObj(Object obj) {
        this.obj = obj;
    }
    public int getState() {
        return state;
    }
    public void setState(int state) {
        this.state = state;
    }
    public String getMsg() {
        return msg;
    }
    public void setMsg(String msg) {
        this.msg = msg;
    }
    public LYResultVO() {
        super();
        // TODO Auto-generated constructor stub
    }
    public LYResultVO(Object obj, int state, String msg) {
        super();
        this.obj = obj;
        this.state = state;
        this.msg = msg;
    }
    
    
    
    public LYResultVO(int state, String msg) {
        super();
        this.state = state;
        this.msg = msg;
    }
    public static LYResultVO errorResultVO(String msg){
        return new LYResultVO(1,msg);
    }
    
    public static LYResultVO successResultVO(Object obj,String msg){
        return new LYResultVO(obj,0,msg);
    }
}

四、启动打包注意事项

启动打包，注意数据库配置，端口配置是否正确。尽量减少这样类型的错误。浪费时间

五、 springboot redis 引入
