调试
1. 打印SQL
2. 设置Debug模式
快速开发

调试

打印SQL

如何在开发过程中输出SQL

下载插件 Mybaits Log Plugin Free
设置配置文件

mybatis:
  # spring boot集成mybatis的方式打印sql
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

设置Debug模式

在log4j2.xml里设置level为debug, 调试完毕改回info, 或者本地调试但不提交代码到云端.

<loggers>
    <root level="debug">
        <appender-ref ref="java"/>
        <appender-ref ref="Console"/>
    </root>
    <logger name="服务名" level="debug" additivity="false">
        <appender-ref ref="FILE.INFO"/>
        <appender-ref ref="FILE.WARN"/>
        <appender-ref ref="FILE.ERROR"/>
        <appender-ref ref="FILE.DEBUG"/>
    </logger>
    <logger name="服务名" level="debug" additivity="false">
        <appender-ref ref="encrypt"/>
    </logger>
</loggers>

自动生成实体类及查询条件类Example

在资源文件夹下设置 generator-config.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    <context id="Mysql" targetRuntime="MyBatis3" defaultModelType="flat">

        <!-- 自动检查关键字，为关键字增加反引号 -->
        <property name="autoDelimitKeywords" value="true"/>
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!--覆盖生成XML文件-->
        <plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />
        <!-- 生成的实体类添加toString()方法 -->
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>

        <!-- 不生成注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/wikidev?serverTimezone=Asia/Shanghai"
                        userId="wikidev"
                        password="666666">
        </jdbcConnection>

        <!-- domain类的位置 -->
        <javaModelGenerator targetProject="src\main\java"
                            targetPackage="com.jungle.wiki.domain"/>

        <!-- mapper xml的位置 -->
        <sqlMapGenerator targetProject="src\main\resources"
                         targetPackage="mapper"/>

        <!-- mapper类的位置 -->
        <javaClientGenerator targetProject="src\main\java"
                             targetPackage="com.jungle.wiki.mapper"
                             type="XMLMAPPER"/>
        <table tableName="ebook"/>
    </context>
</generatorConfiguration>

设置 mybatis-generator Maven文件

设置目录: 项目目录

设置命令: mybatis-generator:generate -e

在 generator-config.xml 文件里设置需要生成的实体类, 就可以自动生成查询条件类

<table tableName="ebook"/>

生成的类文件结构如下图：

生成实体类: Ebook

记得自己加上@Data

package com.jungle.wiki.domain;

import lombok.Data;

@Data
public class Ebook {
    private Long id;

    private String name;

    private Long category1Id;

    private Long category2Id;

    private String description;

    private String cover;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {

    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Long getCategory1Id() {
        return category1Id;
    }

    public void setCategory1Id(Long category1Id) {
        this.category1Id = category1Id;
    }

    public Long getCategory2Id() {
        return category2Id;
    }

    public void setCategory2Id(Long category2Id) {
        this.category2Id = category2Id;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getCover() {
        return cover;
    }

    public void setCover(String cover) {
        this.cover = cover;
    }

    public Integer getDocCount() {
        return docCount;
    }

    public void setDocCount(Integer docCount) {
        this.docCount = docCount;
    }

    public Integer getViewCount() {
        return viewCount;
    }

    public void setViewCount(Integer viewCount) {
        this.viewCount = viewCount;
    }

    public Integer getVoteCount() {
        return voteCount;
    }

    public void setVoteCount(Integer voteCount) {
        this.voteCount = voteCount;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(getClass().getSimpleName());
        sb.append(" [");
        sb.append("Hash = ").append(hashCode());
        sb.append(", id=").append(id);
        sb.append(", name=").append(name);
        sb.append(", category1Id=").append(category1Id);
        sb.append(", category2Id=").append(category2Id);
        sb.append(", description=").append(description);
        sb.append(", cover=").append(cover);
        sb.append(", docCount=").append(docCount);
        sb.append(", viewCount=").append(viewCount);
        sb.append(", voteCount=").append(voteCount);
        sb.append("]");
        return sb.toString();
    }
}

生成对应的Mapper EbookMapper

记得加上@Mapper

package com.jungle.wiki.mapper;

import com.jungle.wiki.domain.Ebook;
import com.jungle.wiki.domain.EbookExample;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import java.util.List;

@Mapper
public interface EbookMapper {
    long countByExample(EbookExample example);

    int deleteByExample(EbookExample example);

    int deleteByPrimaryKey(Long id);

    int insert(Ebook record);

    int insertSelective(Ebook record);

    List<Ebook> selectByExample(EbookExample example);

    Ebook selectByPrimaryKey(Long id);

    int updateByExampleSelective(@Param("record") Ebook record, @Param("example") EbookExample example);

    int updateByExample(@Param("record") Ebook record, @Param("example") EbookExample example);

    int updateByPrimaryKeySelective(Ebook record);

    int updateByPrimaryKey(Ebook record);
}

解决跨域问题

根据实际情况设置!!!

package com.jungle.wiki.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOriginPatterns("*")
                .allowedHeaders(CorsConfiguration.ALL)
                .allowedMethods(CorsConfiguration.ALL)
                .allowCredentials(true)
                .maxAge(3600); // 1小时内不需要再预检（发OPTIONS请求）
    }

}

Spring Boot 进行测试

在测试类上加入对应注解

在被测试的接口上加上‘@Tests’

测试类:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = OrderProviderApplication.class)
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class, DbUnitTestExecutionListener.class})
@Component

测试接口:

@Test

实例:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = OrderProviderApplication.class)
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class, DbUnitTestExecutionListener.class})
@Component
public class ControllerTest extends TestCase {

    @Resource
    Controller Controller;

    @Test
    public void testWarehouseQuery() 
        Controller.testMethod();
    }
}
