随着jeecg-boot不断拓展更新，爱好者越来越多，对于刚入门或者刚从事java(springboot)的人来说，会遇到各种各样的问题。

今天就对jeecg-boot开源项目上的一个issues:373,写个手册-jeecg-boot下多模块项目。

从issues:373 ，可以看出提问者，他想新建一个jeecg-boot-module-jm bundle，然后在 jeecg-boot-module-system 中依赖这个模块。

前提条件：jeecg-boot-module-system 能成功编译，并且jeecg-boot-module-system能成功启动

(数据库、redis配置正确)

jeecg-boot新建module模块

新建maven项目

新建maven项目取名jeecg-boot-module-jm

可以采用idea、myeclipse 等工具来新建一个maven项目

其中 pom.xml文件内容如下

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <artifactId>jeecg-boot-module-jm</artifactId>
    <version>2.0.2</version>

    <parent>
        <groupId>org.jeecgframework.boot</groupId>
        <artifactId>jeecg-boot-parent</artifactId>
        <version>2.0.2</version>
    </parent>

    <repositories>
        <repository>
            <id>aliyun</id>
            <name>aliyun Repository</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>jeecg</id>
            <name>jeecg Repository</name>
            <url>http://maven.jeecg.org/nexus/content/repositories/jeecg</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    
    <dependencies>
        <dependency>
            <groupId>org.jeecgframework.boot</groupId>
            <artifactId>jeecg-boot-base-common</artifactId>
        </dependency>
    </dependencies>
    
    <!-- <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build> -->
</project>

注意：我这个pom文件直接复制了jeecg-boot-module-system 内容，将jeecg-boot-module-system名称改为jeecg-boot-module-jm，注意注释了

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

这段代码，因为新建的项目要打包为jar在jeecg-boot-module-system引用，所以不需要把该项目打包一个springboot项目，注释上面的代码就可以了。

创建业务包

在项目根目录新建包名org.jeecg.modules.hello(以issues：373为例，也可以使用其他包名，记住这个包名，后面在接口问题swagger-ui使用到)

添加业务(测试)代码

(以issues：373为例，后面针对提出的问题，进行一一解答)这段代码后面在swagegr-ui中访问不到，因为方法上没有添加@ApiOperation

package org.jeecg.modules.hello;

import org.jeecg.common.api.vo.Result;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import lombok.extern.slf4j.Slf4j;

/**
 * 测试新的module
 * @author chengtg
 *
 */
@Slf4j
@Api(tags="新建module--jm")
@RestController
@RequestMapping("/hello")
public class HelloController  {
    @GetMapping(value="/")
    public Result<String> hello(){
        Result<String> result = new Result<String>();
        result.setResult("hello word!");
        result.setSuccess(true);
        return result;
    }
}

注意：我修改了注释(@Api(tags="新建module--jm"))，后面在swagegr-ui文档用到

将新建的项目纳入parent中

将新建的jeecg-boot-module-jm 纳入jeecg-boot-parent中

在jeecg-boot-framework项目中的pom文件 modules中添加<module>jeecg-boot-module-jm</module>

结果如下代码

<modules>
    <module>jeecg-boot-base-common</module>
    <module>jeecg-boot-module-system</module>
    <module>jeecg-boot-module-jm</module>
</modules>

添加项目依赖

在jeecg-boot-module-system项目中依赖 jeecg-boot-module-jms

修改jeecg-boot-module-system项目的pom文件

<dependencies>
        <dependency>
            <groupId>org.jeecgframework.boot</groupId>
            <artifactId>jeecg-boot-base-common</artifactId>
        </dependency>
        <dependency>
            <groupId>org.jeecgframework.boot</groupId>
            <artifactId>jeecg-boot-module-jm</artifactId>
            <version>2.0.2</version>
        </dependency>
</dependencies>

编译整个jeecg-boot-framework

如果编译如下：

[INFO] --- maven-install-plugin:2.5.2:install (default-install) @ jeecg-boot-module-system --- [INFO] Installing /Users/chengtg/WS-platform/jeecg-boot-framework/jeecg-boot-module-system/target/jeecg-boot-module-system-2.0.2.jar to /Users/chengtg/.m2/repository/org/jeecgframework/boot/jeecg-boot-module-system/2.0.2/jeecg-boot-module-system-2.0.2.jar [INFO] Installing /Users/chengtg/WS-platform/jeecg-boot-framework/jeecg-boot-module-system/pom.xml to /Users/chengtg/.m2/repository/org/jeecgframework/boot/jeecg-boot-module-system/2.0.2/jeecg-boot-module-system-2.0.2.pom [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary for jeecg-boot-parent 2.0.2: [INFO] [INFO] jeecg-boot-parent ..................................

说明，新建项目jeecg-boot-module-jm并在jeecg-boot-module-system中依赖，成功！

启动jeecg-boot-module-system项目
访问接口文档swagger

http://localhost:8080/jeecg-boot/doc.html

截图如下：

问题来了：为什么新添加的HelloController中@Api(tags="新建module--jm")没有显示

原因查看Swagger2Config配置，Swagger2Config.java

因为截图中红色圈出来的部分

//加了ApiOperation注解的类，才生成接口文档
.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))

表示只有在controller类的方法上要添加ApiOperation注解的，否则是不生成swagegr-ui文档

修改HelloController代码

修改jeecg-boot-module-system-jm项目HelloController类，给hello方法添加ApiOperation注解

package org.jeecg.modules.hello;

import org.jeecg.common.api.vo.Result;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import lombok.extern.slf4j.Slf4j;

/**
 * 测试新的module
 * @author chengtg
 *
 */
@Slf4j
@Api(tags="新建module--jm")
@RestController
@RequestMapping("/hello")
public class HelloController  {
    @ApiOperation("测试hello方法")
    @GetMapping(value="/")
    public Result<String> hello(){
        Result<String> result = new Result<String>();
        result.setResult("hello word!");
        result.setSuccess(true);
        return result;
    }
}

重新编译启动。

再次访问接口文档swagger：http://localhost:8080/jeecg-boot/doc.html

奇迹出现了

测试接口-调试

结果如上出现错误，因为被shiro拦截了

去掉token拦截限制

如果不需要token可以访问，可以在jeecg-boot-module-system项目中修改ShiroConfig.java配置类

代码如下：

import java.util.LinkedHashMap;

}

编译并重启服务，

再次访问接口文档http://localhost:8080/jeecg-boot/doc.html

至此，新建一个module，且测试成功！

回顾下主要步骤：

1.新建一个module maven项目，取名为jeecg-boot-module-jm，修改pom文件

controller中类和方法都需要添加注解：其中类@Api(tags="新建module--jm")，方法@ApiOperation("测试hello方法")

2.将jeecg-boot-module-jm放入jeecg-boot-framework 的modules中

3.jeecg-boot-module-system依赖新添加的maven项目

4.如果不需要拦截，修改jeecg-boot-module-system配置类ShiroConfig.java

拓展:swagger-ui分组

如果想将新建的module 在swagger中以分组形式展现，可以参考如下配置Swagger2Config.java

编译启动，访问swagger-ui文档：http://localhost:8080/jeecg-boot/doc.html

如图：
