Swagger不会生成JSON

Question

Swagger不会生成JSON文件。我的样子POM是这样的：

<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">

        </dependency>

</project>

这是我实现的REST接口：

@Path("/data")
@SessionScoped
@Api(value = "data")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class Data implements Serializable {
    private static final long serialVersionUID = 1L;

    @EJB
    private DataApi d;

    @GET
    @ApiOperation(value = "Returns all data")
    public Collection<DataObject> getData() {
        // Removed.
    }

    @GET
    @Path("{id}")
    @ApiOperation(value = "Returns data by id")
    public DataObject getData(@PathParam("id") Long id) {
        // Removed.
    }
}

我删除了潜在的敏感信息。现在当我按mvn clean install构建项目时，没有生成JSON文件。我没有使用任何JAX-RS实现，只是简单的servlet。我不确定这是否有效。我错过了什么？

Answer 1

刚刚发现至少两个问题。解决问题后，使用mvn clean compile命令生成JSON文件。

1。 pom.xml：build：pluginManagement vs plugins

pluginManagement有swagger-maven-plugin定义，但实际上没有使用它。有必要在plugins中包含另外插件引用：

<project ...>
    <build>
        <pluginManagement>
            ...
        </pluginManagement>

        <plugins>
            <plugin>
                <groupId>com.github.kongchen</groupId>
                <artifactId>swagger-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

2。 locations规范

当前实现中遗漏了location元素，但它必须在此处：

  

可以在此处配置包含Swagger注释@Api的类或包含这些类的包。必须用逗号分隔多个值。示例：<locations><location>com.github.kongchen.swagger.sample.wordnik.resource</location><location>com.github.kongchen.swagger.sample.wordnik.resource2</location></locations>

     

- GitHub - kongchen/swagger-maven-plugin: JAX-RS & SpringMVC supported maven build plugin, helps you generate Swagger JSON and API document in build phase.

总而言之，必须更正locations规范，例如，如下所示：

<locations>
    <location>com.thecompany.service.Data</location>
</locations>

希望这有帮助。
